Abstract:
Based on the fully relativistic spin-polarized screened Korringa-Kohn-Rostoker method and the Kubo-Greenwood equation as formulated for layered systems the interlayer exchange coupling (IEC) as well as the magneto-resistance (MR) for the current in-plane (CIP) geometry is calculated for Fe/Cr/Fe trilayer systems. For the IEC not only short periods of 2 monolayers (ML) but also long periods of about 18 ML are found. For large Cr thicknesses the magnetic moments oscillate with a period of 8-9 ML for even numbers of Cr layers and 18 for odd. The calculated CIP MR and corresponding resistivities are in the ran-e of available experimental data. It is found that the peaks in the CIP MR have little in common with the oscillation periods characterizing the IEC.
