Electronic Properties of Mn3Z (Z = Ga, Ge) Alloys: Studies from First Principles

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

Structural and electronic properties of Mn3Z alloys (Z = Ga, Ge) are studied ab initio. It is shown that in the cubic and tetragonal phases, the configuration with antiparallel orientation of magnetic moments of Mn atoms on different sublattices is energetically advantaheous. Calculations of the electronic densities of states show that the spin polarization of the tetragonal phase is around 60%. The obtained results are in good agreement with experimental data.
