First-principles calculation of the effect of atomic disorder on the electronic structure of the half-metallic ferromagnet NiMnSb
TLDR
In this article, the electronic structure of the half-metallic ferromagnet NiMnSb with three different types of atomic disorder is calculated using the layer Korringa-Kohn-Rostoker method in conjunction with the coherent potential approximation.Abstract:
The electronic structure of the half-metallic ferromagnet NiMnSb with three different types of atomic disorder is calculated using the layer Korringa-Kohn-Rostoker method in conjunction with the coherent potential approximation. Results indicate the presence of minority-spin states at the Fermi energy for degrees of disorder as low as a few percent. The resulting spin polarization below 100% is discussed in the light of experimental difficulties confirming the half-metallic property of NiMnSb thin films directly.read more

Simple rules for the understanding of Heusler compounds
TL;DR: Heusler compounds as discussed by the authors are a remarkable class of intermetallic materials with 1:1:1 or 2:1-1 composition comprising more than 1500 members, and their properties can easily be predicted by the valence electron count.
