Query: DFT calculations of magnetic anisotropy energy for GeMnTe ferromagnetic
  semiconductor   Density functional theory (DFT) calculations of the energy of magnetic
anisotropy for diluted ferromagnetic semiconductor GeMnTe were performed using
using OpenMX package with fully relativistic pseudopotentials. The influence of
hole concentration and magnetic ion neighborhood on magnetic anisotropy energy
is presented. Analysis of microscopic mechanism of magnetic anisotropy is
provided, in particular the role of spin-orbit coupling, spin polarization and
spatial changes of electron density are discussed. The calculations are in
accordance with the experimental observation of perpendicular magnetic
anisotropy in rhombohedral GeMnTe (111) thin layers.
