Abstract

In using the fully relativistic versions of the Screened Korringa-Kohn-Rostoker method and of the Kubo-Greenwod equation domain wall resistivities at the equilibrium domain wall width are calculated for NicFe1-c. It is found that in comparison to the corresponding "bulk" case only between about 0.6¡Ü c<1 the anisotropic magnetoresistance is reduced in the presence of a domain wall sufficiently enough in order to be of practical use for potential race track memories. Around 80% Ni this reduction amount to remarkable 16%!
