摘要：

The effects of Sn addition on phase transformation behavior and magnetocaloric properties of Mn50Ni25Ga25-xSnx (x=0, 0.1, 0.5, 1 and 2 at%) alloys were investigated in this work. Delta M/Delta S obviously increase with increase in the Sn contents, implying the higher efficiency shift of the martensitic transformation temperature under the magnetic field.
