Ternary Diagrams of Ni-Mn-Ga from First Principles

Abstract:

The composition dependences of the magnetic and elastic properties of Ni-Mn-Ga Heusleralloys are investigated by using ab initio calculations. The off-stoichiometric compositions are real-ized by the coherent-potential approximation. Two types of off-stoichiometric approaches are pro-posed. Through a series of researches, the equilibrium lattice constants, bulk modulus, magnetic mo-ments, formation energies of Ni-Mn-Ga alloys are obtained and mapped onto ternary diagrams.
