Tailoring martensitic transformation and martensite structure of NiMnIn alloy by Ga doping In

► The crystal structures at room temperature for Ni50Mn34In16−xGax (x = 0-16) alloys are studied. ► The mechanism for the martensitic transformation temperature variation with Ga content is analyzed. ► The Curie temperature for austenite and martensite are measured, showing different change tendency with Ga content.
