Abstract

The martensitic and magnetic transitions of Ni₅₄Ga₂₇Fe₁₉ alloy were investigated by differential scanning calorimetry and X-ray powder diffraction and with a vibrating sample magnetometer. The alloy is martensitically transformed from a L2₁ to a martensite phase with a 14M (7R) structure. The ferromagnetic transition is also accompanied by the martensitic transformation from a paramagnetic parent phase to a ferromagnetic martensite phase in the temperature interval between M_s (= 293 K) and M_f (= 274 K). The Ni-Ga-Fe system is promising as a ferromagnetic shape memory alloy.
