English abstract:
The fully relativistic screened Korringa-Kohn-Rostoker method is used to discuss the electronic structure
and magnetic properties of FexMn12x overlayers on Cu~100!/Co. It is found that in this system, energetically
low-lying antiferromagnetic configurations most likely are the cause for the experimentally observed antiferromagnetism.
In all cases investigated, the ground state corresponds to the ~in-plane! ferromagnetic configuration;
the FexMn12x overlayers do carry a small ~concentration averaged! magnetic moment. In very good
agreement with experiment, two overlayer thicknesses, namely, at 3 and 10 ML, are traced, at which either this
moment nearly vanishes ~3 ML! or different types of antiferromagnetic configurations apply ~10 ML!.
