• Magnetic moment

Permeability, magnetization and differential scanning calorimetry measurements are carried out on Pd2Mn1+xSn1-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 Pd2Mn1+xSn1-x has the characteristics of the phase diagrams of Ni(2)Mn(1+x)Z(1-x) (Z = In, Sn) metamagnetic shape memory alloys.
