Magnetic materials are one of the fastest growing areas of research in the field of nanotechnology.  In the paste decades magnetic thin films and nanostructures got into the focus of solid state physics due to their promise in development of spintronic devices.

The Korringa-Kohn-Rostoker (KKR) method within the local density approximation (LDA) of the density functional theory could be successfully applied to describe the electronic and magnetic structure of transition metal thin films and deposited clusters. The study of new two-dimensional magnetic materials, such as chalcogenides, transition metal selenides, requires a step behind LDA to explore the properties of such a  systems. A possible way of the extension of the KKR method is the inclusion of the self interaction correction (SIC) into the electronic structure calculation. The PhD student should review different implementations of SIC and embed a suitable one into our existing KKR code. With the help of the new procedure electronic structure of 2D magnets should be explored. The finite temperature behavior of thin films should be investigated by means of Monte Carlo simulations based on the exchange and anisotropy parameters obtained by the new version of the KKR method.
