Layer-resolved optical conductivity of Co|Pt multilayers

Abstract

The complex optical conductivity tensor is calculated for the Co|Pt systems by applying a contour integration technique within the framework of the spin-polarized relativistic screened Korringa-Kohn-Rostoker method. It is shown that the optical conductivity of the Co|Pt multilayer systems is dominated by contributions arising from the Pt cap and/or substrate layers.Comment: 7 pages (LaTeX), 2 (a,b) figures (Encapsulated PostScript), J.
