Martensitic transformation,Magnetic-field-induced martensitic transformation

Mn₃Ga alloys transform from the weakly magnetic D0₁₉ phase to the strongly magnetic monoclinic phase. We investigated the feasibility of magnetic-field-induced martensitic transformation and evaluated the magnetic hysteresis.
