Permeability, magnetization and differential scanning calorimetry measurements are carried out on Pd 2 Mn 1+ x Sn 1− x (0 ⩽ x ⩽ 0.50). On the basis of the experimental results, the phase diagram in the temperature–concentration plane is determined. The determined phase diagram is spanned by a paramagnetic austenite phase (P–A), a paramagnetic martensite phase (P–M), a ferrimagnetic austenite phase (F–A) and a martensite phase (F–M) with a small spontaneous magnetization. It is found that Pd 2 Mn 1+ x Sn 1− x has the characteristics of the phase diagrams of Ni 2 Mn 1+ x Z 1− x ( Z = In, Sn) metamagnetic shape memory alloys. |
