Abstract

A new ternary compound (Ni, Mn)₂Ga was identified in Ni-Mn-Ga system by a combination of powder X-ray diffraction, differential thermal analysis and electron probe microanalysis. The (Ni, Mn)₂Ga phase was determined with a Mn₂Ge-type hexagonal structure, with lattice parameters of a = 4.1629(8) nm, c = 5.2983(9) nm, and unit cell volume of 0.07952(4) nm³ after refinement. The reversible phase transformation from (Ni, Mn)₂Ga hexagonal structure to bec (B2) cubic structure at high temperature was suggested by DTA measurements. The transformation peaking temperatures during heating and cooling are 834.0 °C and 815.8 °C for Mn₄₀Ni₂₅Ga₃₅, 804.7 °C and 774.1 °C for Mn₅₀Ni₁₇Ga₃₃, respectively.
