Calculation of the layer-resolved optical conductivity for magnetic multilayers and surface layer systems — •A. Perlov¹, T. Huhne², and H. Ebert² — ¹MPI für Physik komplexer Systeme, Nothnitzer Str. 38, 01187 Dresden — ²Inst. für Physik. Chemie, Universität München, Theresienstr. 37-41,D-80333 München, Germany

A scheme is presented that allows to split the optical conductivity tensor for a magnetic multilayer system into contributions stemming from individual atomic layers. It is demonstrated that the layer projected optical conductivity tensor is related to the electronic properties of only some few neighboring layers. This property allows to predict the magneto-optical properties of rather complex systems if the magneto-optical properties of its basic units are known from a calculation for a closely related but simpler system. The use of this approach to investigate the magneto-optical properties of magnetic surface layers on top of a non-magnetic substrate is demonstrated for some transition metal systems. For this purpose a suitable multilayer system is used as a reference system with its magneto-optical properties calculated using the relativistic spin-polarized version of the LMTO-method of band structure calculation.
