Ab–initio calculation of Kerr spectra for semi–infinite systems — •András Vernes1, László Szunyogh1,2, and Peter Weinberger11Center for Computational Materials Science, Technical University Vienna, Vienna, Austria — 2Department of Theoretical Physics, Budapest University of Technology and Economics, Budapest, Hungary

Based on Luttinger’s formulation the complex optical conductivity tensor is calculated within the framework of the spin–polarized relativistic screened Korringa–Kohn–Rostoker method for layered systems by means of a contour integration technique. For polar geometry and normal incidence ab–initio Kerr spectra of multilayer systems are then obtained by including via a 2× 2 matrix technique all multiple reflections between layers and optical interferences in the layers.
