Abstract

Permeability and differential scanning calorimetry measurements were carried out on Ni2MnGa1-xFex(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+xMn1-xGa,Ni2Mn1-xCuxGa and Ni2MnGa1-xCux 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 Ni2MnGa1-xFe x(0≤x≤0.375) is also reported.
