In this paper, we investigate the magnetic and martensitic transformation properties of Cu doping partial Ni in Ni50Mn36In14 alloy. It is found that the critical temperature of the martensitic transformation decreases with Cu concentration x in Ni50-xCuxMn36In14 increases. While Cu concentration is less than 5% at., the magnetization of austenite phase is stronger than that of martensite phase, and ΔM of magnetization martensite and austenite increases with Cu doping. ΔM increases rapidly to 80 emu/g when x=4.5 and a field-induced transformation is observed in this alloy, predicting the application potential as the magnetic actuation and magnetoresistance materials. As Cu content increases to x > 5, the magnetization of austenite becomes weaker than that of martnensite, ΔM decreases to near zero.
