Abstract

Permeability and differential scanning calorimetry measurements were carried out on Ni₂MnGa_1-xFe_x(0≤x≤0.40). On the basis of the experimental results, the phase diagram in the temperature-concentration plane was determined. The characteristics of the determined phase diagram are similar to those of the phase diagrams of Ni _2+xMn_1-xGa,Ni₂Mn_1-xCu_xGa and Ni₂MnGa_1-xCu_x systems, where the magnetostructural transition between the paramagnetic austenite phase (Para-A) and ferromagnetic martensite phase (Ferro-M) occurs. Furthermore, the concentration dependence of the magnetic moment per formula unit, ^μs, at 5 K for Ni₂MnGa_1-xFe _x(0≤x≤0.375) is also reported.
