Magnetic hysteresis loops measured at 5 K for Mn3−xFexGa samples treated at (a) 623 K, (b) 883 K and (c) 1073 K; (d) the coercive field as a function of Fe content for samples treated at 623 and 883 K; (e) the magnetization under a field of 50 kOe at 5 K as a function of Fe content; (f) the Curie temperature TC as a function of Fe content for the tetragonal Mn3−xFexGa alloy, and the inset shows the M–T curves of Mn3Ga, showing the tangent method for determining TC.
