Resumo

The 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 favorable. Calculations of the electronic densities of states show that the spin polarization of the tetragonal phase is about 60%. The results obtained are in good agreement with the experimental data.
