Electronic Structure and Martensitic Transformation in Ni$\text{}_{2}$ MnGa Heusler Alloy

The electronic structure of the Ni$\text{}_{2}$MnGa Heusler alloy has been investigated for martensitic transformation β$\text{}_{1}$ → β'$\text{}_{1}$ → β"$\text{}_{1}$ → β'''$\text{}_{1}$ by the self-consistent TB-LMTO method. The distortion influences the shape of the densities of states. The β$\text{}_{1}$ is the most stable phase. We present the values of total and local magnetic moments for all phases of Ni$\text{}_{2}$MnGa alloy
