A new ternary compound (Ni, Mn)(2)Ga 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)(2)Ga 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) nm(3) after refinement The reversible phase transformation from (Ni, Mn)(2)Ga hexagonal structure to bcc (B2) cubic structure at high temperature was suggested by DTA measurements. The transformation peaking tempera
