Abstract

The nature of unique magnetic properties and martensitic transformation of Ni ₂Mn _1xIn _1-x shape memory alloy has been revealed by first-principles calculations. The uncommon magnetic properties occurring upon martensitic transformation are originated from the change of Mn-Mn interatomic distances. The critical value of Mn-Mn interatomic distance corresponding to the change of magnetic interactions has been determined. A decrease of the intensity of Ni 3d states at the Fermi level upon martensitic transformation has been observed for x 0.5. Moreover, the Ni 3d-Mn 3d hybridization plays an important role in establishing the magnetic properties and driving the martensitic transformation.
