Abstract

Heusler alloy Mn2 NiGa has been developed by synthesizing a series of ferromagnetic shape memory alloys Mn25+x Ni50-x Ga25 (x=0-25). Mn2 NiGa exhibits a martensitic transformation around room temperature with a large thermal hysteresis up to 50 K and a lattice distortion as large as 21.3% and has a quite high Curie temperature of 588 K. The martensite shows a high-saturated field up to 2 T. The excellent two-way shape memory behavior with a strain of 1.7% was observed in the single crystal Mn2 NiGa. The magnetic-field-controlled effect created a total strain up to 4.0% and changed the sign of the shape deformation effectively.
