A New Titanium-Based Heusler Alloy

Abstract:

The Heusler alloy system is a rich source of functional materials. We studied the ternary alloy Ti₂NiSb by first-principles calculations to explore for new functional alloy. We performed geometry optimization for the alloy with Hg₂CuTi-type structure and the obtained equilibrium lattice parameter is a₀=6.21 Å. The magnetic moments of atom Ni is 0.22μ_B in one cell. The alloy is a ferromagnet. The little magnetic moment of atom Ni comes from the characteristic spatial occupation of the atoms in the space structure of the alloy.
