Abstract

Differential scanning calorimetry (DSC) and magnetic measurements were performed to study the influence of ferromagnetic 3-d transition elements Fe and Co on structural and magnetic properties of ferromagnetic shape memory alloys Ni₂MnGa. Addition of Fe or Co on the Ni sites decreases the temperature of martensitic phase transition T_m, whereas addition of Co on the Mn sites results in a considerable increase of T_m. Magnetic measurement revealed that Curie temperature T_C increases upon substitution of Fe or Co for Ni. This observation is of importance for design of high temperature ferromagnetic shape memory alloys.
