Magnetism of 4dand 5dadlayers on Ag(001) and Au(001): Comparison between a nonrelativistic and a fully relativistic approach

Abstract
The magnetic properties of single and double layers of Ru, Rh, Pd, Os, Ir, and Pt on Ag(001) and Au(001) are investigated using the scalar relativistic and the fully relativistic spin-polarized screened Korringa-Kohn-Rostoker method. It is shown that, in particular, for the case of the Ir monolayers and Pt double layers a nonrelativistic approach is no longer valid, since a magnetic ground state would be predicted, while a relativistic description yields a nonmagnetic ground state.
