摘要	Heusler-type alloy Co50Ni22Ga28 was synthesized by arc-melting. X-ray diffraction (XRD) results show that the as-cast Co50Ni22Ga28 alloy consists of a main phase of body-centered tetragonal martensite beta and a little fcc gamma phase. The austenitic-martensitic phase transformation was confirmed by DSC, which agreed with corresponding phase transitions determined by M-T curve under 0.01 T. Moreover, magnetic measurements show that austenitic phase has larger magnetization until the applied field is up to 1 T and both martensite and austenite are ferromagnetic at T < 360 K. The maximum of magnetic entropy changes -10.5 J kg(-1) K-1 was observed around austenitic-martensitic phase transformation. (C) 2008 Elsevier B.V. All rights reserved.
