Half-metallic properties for the Mn_2FeZ(Z=AI, Ga, Si, Ge, Sb) Heusler alloys: A first-principles study

摘要

The electronic structure and magnetism of the Mn_2FeZ (Z=A1, Ga, Si, Ge, Sb) Heusler alloys have been studied by density functional calculations. Two half-metallic ferromagnets, namely, Mn_2FeAl and Mn_2FeSb, are predicted. It is found that a small expans
