Research objectives and content
The project will provide a theoretical, microscopic framework for the interpretation of measured and simulated properties of the magnetization dynamics of nanomagnets. The experiments of irnmediate interest are currently being carried out at French and Spanish laboratories, some of which enjoy EC funding. The interpretation and predictions will mainly come from computer simulation studies of appropriate models of the magnetic materials, using the most advanced computing facilities. The experimental study, simulation and interpretation of the magnetization dynamics of very small magnetic particles is important for technological applications to magnetic storage devices and to fundamental science. The focus of the work will be on the development of computer simulation methods to calculate the response of the magnetization to a changing applied field. The aim is to get insight into the phenomena that govern the reversal of the magnetization in small magnetic particles and to study the transition from microscopic dynamics to macroscopic behavior. The work prograrnme will build on recent work carried out by the project manager, in collaboration with Spanish and Japanese researchers. Preliminary investigations have been supported by EC funds through a HCM network grant. As the candidate will be exposed to several European research institutes through his work, the project will contribute to the dissemination of knowledge to other EC member states.
Training content (objective, benefit and expected impact)
The candidate will receive training in the fields of magnetism and non equilibriurn statistical mechanics. Furthermore he will enlarge his repertoire of computer simulation techniques. The knowledge acquired through his participation in the project will be of immediate interest to the German physics community.
