1. Summary for public relations work

Magnetic materials are a vital part of daily life. From cars, desktop PCs to small gadgets –

magnets play an essential role. In hybrid cars, permanent magnets are used in motors and

generators. High-performance magnets improve their performance and energy efficiency.

The development of low emission cars goes hand in hand with the optimization of permanent

magnets. The information and communication society requires increasing data storage

capacity. Magnetic media account for 92% of all newly stored information. Electronic data

storage is no longer done on computers only. Consumer electronic devices are expected to

store and replay data in form of music, video, and images. Magnets have a wide range of

application areas. In all fields a detailed understanding of how the magnet works - how its

power can be improved - leads better performance, higher energy efficiency and higher

quality of life for the citizens of modern society.

Computer simulations precisely describe the magnetization processes on a length scale

thousand times smaller than the thickness of a human hair. The atomistic magnetic moments

– like tiny little compass needles – arrange themselves according the chemical / physical

structure of the magnet. The microstructure might be quite complex. At high magnification,

the particles of a hard disk, a hundred of which are used to encode a bit, look like rows of

rocks under the electron microscope. Within each particle, thousands of tiny compass

needles change their direction as imposed by the magnetic field of the write head. Because

the structure of the materials is in no way regular, it can only be described by equations with

computational methods. In this way predictions about the magnetic behavior of a material are

possible and can be compared with the experimentally observed properties.

The development of a software package for the simulation of magnetization dynamics taking

into account the complex microstructure led to major breakthroughs in different fields of

applied magnetism. The use of state-of-the-art numerical methods makes the developed

software to be the fastest and most precise software package that is currently available for

the optimization of magnetic devices. Fast field calculation methods make use of techniques

that are very similar to the compression of images or videos on a computer. Your future hard

disk may have been designed by use of the software developed in this project. Magnetic

storage will reach a storage density of a trillion bits per square centimeters. The current road

map envisions a special recording material: Hard and soft magnetic layers that are coupled

to each other, a structure developed within this project. Computer techniques developed

within this project are also used to optimize permanent magnets for use in low emission,

hybrid cars.


Zusammenfassung

Magnetische Werkstoffe sind aus dem heutigen Leben nicht mehr wegzudenken. Von Autos

über Computer bis hin zu technischen Geräten – Magnete spielen eine grundlegende Rolle.

In Hybridautos werden Permanentmagnete in Motoren und Generatoren eingesetzt.

Hochleistungsmagnete verbessern ihre Leistungsfähigkeit und Energieeffizienz. Die

Entwicklung von Niederemissionsautos geht Hand in Hand mit der Optimierung von

Permanentmagneten. Die Informations- und Kommunikationsgesellschaft hat einen ständig

wachsenden Bedarf an Datenspeicher. Auf magnetische Medien entfallen 92% aller neu

gespeicherten Daten. Nicht nur Computer, auch Kleingeräte aus der Unterhaltungselektronik

speichern und geben heute Daten in Form von Musik, Videos und Bildern wieder. Magnete

haben vielfältige Anwendungsgebiete, in denen ein detailliertes Verständnis ihrer

Funktionsweise – die Erhöhung der Leistungsfähigkeit – zu höherer Energieeffizienz führt

und damit die Lebensqualität in einer modernen Gesellschaft steigern kann.

Computersimulationen beschreiben präzise den Magnetisierungsprozess auf einer

Größenskala, die tausend Mal kleiner ist als eine Haaresbreite. Die atomistischen

magnetischen Momente – vergleichbar mit winzigen Kompassnadeln – richten sich nach der

chemisch-physikalischen Struktur des Magnets aus. Die Mikrostruktur kann sehr komplex

sein. Bei hoher Vergrößerung sehen die Körner einer Festplatte, von denen man etwa

hundert benötigt um ein Bit zu schreiben, im Elektronenmikroskop aus wie Reihen von

Kieselsteinen. In jedem Korn ändern tausende winziger Kompassnadeln ihre Richtung nach

dem magnetischen Feld des Schreibkopfes. Da die Struktur des Materials keineswegs

gleichmäßig ist, kann sie nur durch Gleichungen mit numerischen Methoden beschrieben

werden. So können Vorhersagen über das Verhalten eines Materials sowie Vergleiche mit

den experimentell beobachteten Eigenschaften gemacht werden.

Die entwickelte Software zur Simulation der Magnetisierungsdynamik unter Beachtung der

Mikrostruktur führte zu bedeutenden Durchbrüchen in verschiedenen Bereichen von

angewandtem Magnetismus. Modernste numerische Methoden machen das Softwarepaket

zum schnellsten und präzisesten derzeit erhältlichen Werkzeug zur Optimierung von

magnetischen Instrumenten. Schnelle Feldberechnungsmethoden verwenden Techniken, die

denen zur Kompression von Bild- und Videodaten sehr ähnlich sind. Ihre nächste Festplatte

kann eventuell mit der in diesem Projekt entwickelten Software entworfen worden sein. Die

magnetische Speicherdichte wird 1 Tbit/cm² erreichen. Das Datenträgermaterial der Zukunft

besteht aus hart- und weichmagnetischen Schichten, die miteinander gekoppelt sind; eine

Struktur, die in diesem Projekt entwickelt wurde. Rechenmethoden, die in diesem Projekt

ausgearbeitet wurden, werden außerdem dazu benutzt, um Permanentmagnete zur

Verwendung in schadstoffarmen Hybridautos zu optimieren.


2. Brief project report

2.1 Report on the scientific work 2.1.1 Information on the development of the research work

The main objective of the project was to provide a software package that uses state-of-the-art numerical techniques for the simulation of the functional behavior of magnetic devices. The simulations should span several length scales, starting from the precise calculation of magnetization processes on the nano-scale that takes into account the local chemical / physical environment to the macroscopic, measurable output of a device that may be composted of several components. At the time when the project proposal was written, the National Institute of Standards and Technology started an effort to validate micromagnetic software, introducing micromagnetic standard problems. The results published on their micromagnetic web-page show that at this time reliable micromagnetic simulations were only possible for small scale (below 500 nm) magnetic nano-structures. The goal of simulating an entire device composed of different magnetic parts, each of which with its own microstructure was quite ambitious at this time and it was by no means clear whether this is possible at all. To accomplish this objective, the work program focused on the investigation of different numerical techniques discussed at this time in the applied mathematic community. Among those were meshless methods, fast boundary element methods, and continuation methods. Whereas the concept of meshless methods is applied in structure mechanics meshless based methods never proved superior in electromagnetic field computation. On the other hand, fast boundary element methods were developed during the course of the project at the University of Kiel and the Max-Planck-Institute of Industrial Mathematic Leipzig. The immediate application of the newly developed hierarchical matrices was a key point for success of the project. At the same time, the transition from longitudinal to perpendicular recording was prepared within major recording companies. Close collaboration with researchers from IBM / Hitatchi GST provided important input on the requirements of micromagnetic software for the simulation of perpendicular recording systems. With respect to the original objectives there was no change of direction during the course of the project. However, the numerical techniques and methods used in the micromagnetic simulations were adjusted to the current state-of-the-art in applied mathematics and in computational physics. Instead of meshless methods for solving partial differential methods a hybrid finite element / fast boundary element scheme [78] is used. Similarly, time quantified Monte Carlo schemes and hybrid Monte Carlo methods were originally proposed in the work program, in order to address long time, thermally activated magnetization processes. Despite the promising reports on time quantified Monte Carlo schemes in magnetism, initial studies carried out in the project showed that this method has severe limitations if applied to realistic, large scale magnetic structures. Instead, we applied the nudged elastic band method, a method popular in chemical physics, in micromagnetic simulations [51]. The micromagnetic calculations of the minimum energy path proved to be extremely successful to address the thermal stability of recording media or to compute the temperature dependence of the coercive field at long time scales. The work carried out was aimed at achieving the objectives of the projects, the simulation of magnetic devices bridging time and length scales over several orders of magnitude. Whenever necessary, alternative numerical techniques were applied to reach the overall objectives.


2.1.2 Most important results and brief description of their significance The key results of the project are the following World leading magnetic simulation software Key inventions for future high density storage media Expanding the knowledge in the following fields

o Permanent magnets o Magnetic recording o Magnetic nanostructures

Magnetic simulation software Micromagnetism is a theory to describe magnetization processes at a significant length scale of several nanometers. Standard micromagnetic software (OMMF from NIST, LLG Simulator from Mindspring) allows the efficient simulations of magnetic structures for simple geometries. Advanced software tools are required to take into account the detailed microstructure of a magnet and the interactions between the different magnetic parts of magnetic device. In addition to the calculation of magnetization reversal processes and the simulation of domain images, the software developed during the project enables the fully integrated simulation of entire magnetic devices. For example in magnetic recording simulations, the input for the simulations are the detailed microstructure of the recording media, the geometry of the write head, the layer stack and shield geometry of the read head, the intrinsic magnetic properties and the current wave form of the write current. The simulation output is read back voltage as function of time. Thus macropscopic properties like current wave form and read back voltage are input and output of a multiscale simulation that treats the functional behavior of a recording system while taking into account the microscopic magnetization processes during recording [93] and read back [123]. This multiscale simulation process is illustrated in Figure 1. This software is currently used in research collaboration with several industrial partners, the Information Storage Industry Consortium, and EU FP6 projects. It is and has been used for the design of recording systems, high performance permanent, and magnetic random access memories. The public domain version of the software (MAGPAR) [66] has been downloaded more than 800 times and is used in universities, research labs, and industry. In addition to OMMF from the National Institute of Standard and Technology, MAGPAR has become a standard for micromagnetic simulations.

Figure 1: Left: Magnetic system used in recording simulations, Right: computed read back signal.


Traditional micromagnetic simulations are limited in the time scale. Whereas fast events like writing on recording media can be computed using standard dynamic micromagnetics, the simulation of the long time behavior requires different methods. During the project the nudged elastic band method has been integrated in the micromagnetics software environment [51], in order to calculate the time and temperature dependence of the coercive field [111]. This is a novel approach and the resulting capabilities are unique, there is no other software package that can calculate the thermal stability of magnetic materials for arbitrary geometries and microstructures. As an example, Figure 2 shows the calculation of energy barriers in longitudinal AFC recording media [70].

Figure 2: Energy barriers can be calculated in complex granular structures. Here the energy barrier for the reversal of a grain embedded in an AFC media was calculated.

Figure 3: Multiscale micromagnetic simulation of recording on exchange spring media.


Key inventions for future high density storage media Future high density storage media require small, thermally stable bits. A possible way to achieve writeable, stable recording media resulted from the research activities during the project [104]. In exchange spring media, magnetically hard and magnetically soft layers are combined, so that the soft magnetic layer reduces the switching field and the hard magnetic layer provides a high energy barrier. Current roadmaps for magnetic recording at densities beyond 2 Tbit/in2 envision exchange spring type media for both granular perpendicular media and bit patterned media.

During the last two year, Dieter Suess was invited to give 13 invited talks and lectures on this topic. Papers of the working group on exchange spring media were cited 32 times since 2005. Recording densities of 1 Tbit/in2 and beyond recording media were demonstrated for in exchange spring based granular media using fully integrated micromagnetic simulations (presentation EB-09, Joint MMM-Intermag conference, January 2007). An example of such simulations is shown in Figure 3 [131].

Permanent magnets

Research in permanent magnets focused on the understanding on the interplay between microstructure and coercivity. Finite element micromagnetics is an excellent means to represent the complex multiphase grain structure of a permanent magnet. The success of this research is reflected by seven invited talks on microstructure property relations in permanent magnets at international conferences. Using a combination of magnetic imaging using Lorentz transmission electron microscopy with micromagnetic simulations we were able to characterize the influence of key microstructural features on coercivity quantitatively.

In particular the role of grain boundaries in NdFeB based sintered magnets [14] and domain wall pinning in Sm2Co17 magnets [41] were investigated. Figure 4 shows TEM images of magnetic domains and computed domain patterns in Nd13.5FebalBB5.95Cu0.03Al0.7 magnets and Sm2Co17 magnets.

Magnetic recording

Software tools for the simulation of the recording process enable the detailed simulations of the various processes involved in magnetic recording. In particular the following key issues were addressed. The results were presented at invited talks at major international conferences.

Soft underlayer magnetization processes in perpendicular recording (North American Conference on Perpendicular Magnetic Recording, 2002)

Head media interactions in perpendicular magnetic recording (North American Perpendicular Magnetic Recording Conference, 2004)

Properties of FePt nanoparticles (L10 Ordered Intermetallic and Related Phases for Permanent Magnet and Recording Applications, 2004)

Optimization of exchange spring media (DISKON 2005, Intermag 2006, APS March meeting 2006, MINT workshop 2006)

Write head dynamics (International Storage Technology Symposium, 2007; TMRC 2007)

Magnetic nanostructures

Magnetic multi-layers are the basic building blocks of spin-electronic devices. The simulation of the magnetization processes provides a quantitative description of the coercive field and the exchange bias field of antiferromagnetic/ferromagnetic bilayers. Again the detailed description of the nanocrystalline structure and its influence on the magnetization processes is the key success of this model. For the first time, exchange bias is explained for fully compensated interfaces [65]. Exchange bias at compensated interfaces occurs in IrMn/FeCo layers which are applied in the read head of magnetic hard discs. Thermally activated magnetization processes determine the properties of magnetic storage and sensor elements with dimensions in the range of a few nanometers. Predictions of the thermal stability of magnetic storage units and the calculation of the thermal noise in magnetic field sensors require a detailed knowledge of the metastable energy minima and of the saddle points of a high dimensional energy landscape. For the first time the energy landscape of high dimensional micromagnetic systems was computed using an elastic band method [82]. An important application is the prediction of the lifetime of bits in magnetic random access memories (Invited talk at the 16th Soft Magnetic Materials Conference, Düsseldorf, 2003).

2.1.3 Information on the running of the project

The duration of the project was seven years. Whereas planned for only six years, additional industrial funding made a prolongation of the project possible. Furthermore during 2005, the original project’s last year, a promising invention was made. Therefore it seemed appropriate to extend the project for one year for more detailed studies on the potential of exchange spring media for perpendicular recording. The high international recognition gained for our research in this field clearly justified this prolongation of the project. Total project costs were split amongst various categories as follows: Personnel 56%Equipment 13%Consumables 1%Travel 8%Other 22%


The two major items of equipment purchased were a local cluster of workstations and an addition to a TEM for Lorentz magnetic imaging. There were no significant deviations from the original proposed use of the available funding. All levels of personnel – master students, PhD students, and post-doc researchers – were used depending on the skills and availability of the individual researchers.

2.2 Personnel development

A key point for success was the possibility to use the available funding for high risk research. At the beginning of the project it was not obvious whether the fully functional simulation of magnetic devices is at all possible. The possibility to spend enough money on certain research topics and the possibility to establish international collaborations to advance a research area were key mechanisms for achieving the project’s objectives. The project provided the funding to establish a working group on micromagnetics at the Vienna University of Technology. The project funded six diploma students, eight PhD students, and four post-docs. The ideas, developments, and achievements of the group members created enough momentum for a clear international recognition of the working group. The international reputation of the project co-workers is high. However, the Vienna University of Technology missed the opportunity to secure the future existence of this newly created high potential working group. As a result of the project The project leader was appointed Professor of Functional Materials

at the University of Sheffield, UK One co-worker is director of a research institute in Greece Three co-workers hold key industrial positions (USA, France) Two co-workers doing their PhD in USA and Ireland (University of Illinois at Urbana-

Champaign, Trinity College Dublin) One co-worker is post-doctoral research assistant in the UK One co-worker is expecting his Habilitation at the Vienna University of Technology

2.3 Effects of the project outside the scientific field
