Abstract
Abstract We present spin-resolved appearance potential spectroscopy (APS) calculations at the 2p3/2 edge of Fe in the high-moment ferromagnetic phase of fcc Fe/Cu(001) overlayers, based on a single-particle description of the underlying electronic structure. Within the framework of the real-space Korringa-Kohn-Rostoker method, the spectra were calculated in a layer-resolved mode. This allows one to investigate in detail the dependence of the total APS signal–a superposition of weighted layer-signals–as a function of the Fe overlayer thickness.
