The electronic structure, martensitic transformation and magnetic properties of [Formula: see text] Heusler alloy were studied by first-principles calculations. It is found that the stable structure of austenitic [Formula: see text] is the ferromagnetic [Formula: see text] structure, and a martensitic transformation is possible to occur with the distortion degree of 1.26. By the analysis of the electronic structure, some results of magnetic moment are consistent with previous theoretical calculations.

Ferromagnetic Shape Memory

Recently, 50-nm Heusler Mn3Al thin films were experimentally synthesized by Jamer et al. [Phys. Rev. Appl. (2017), 7, 064036] and the nominal zero moment, i.e. the fully compensated ferrimagnetic property, of these thin films was confirmed. That work motivated the current investigation on the martensitic transformation, electronic structure and magnetism of D03-ordered Mn3Al using first-principles calculations. Owing to tetragonal distortion, the martensitic transformation only occurs with tensile strain rather than with compressive strain and the half-metallic-type Mn3Al becomes a magnetic metal. Consequently, Mn3Al shows great potential for application as a ferromagnetic shape memory alloy. Moreover, not only did the martensitic transformation occur in Mn3Al, it was also observed in similar D03-ordered Mn3 Z (Z = B, Ga, Ge, Sb) compounds.

The phase stability, electronic structure and magnetism of Pt 2-x Mn 1+x In (x = 0, 0.25, 0.5, 0.75, 1) alloys are studied by first-principles calculations. The possible magnetic martensitic transformation in this series has been investigated. For all the five compounds, the energy minimums occur around c/a = 1.30, and the energy differences between the austenitic and martensitic phases are large enough to overcome the resistance of phase transformation. By comparing the electronic structures of austenitic and martensitic phases, we can find that the phase stability is enhanced by the martensitic transformation. The magnetic structures of the austenitic and martensitic phases are also discussed.
