Crystal structures and magnetic properties of Pt-Mn-Sn alloys have been investigated by means of X-ray and magnetic analysis. It has been found that C1 or C1b type compound PtMnSn exists in the Pt-Mn-Sn system and forms solid solutions in the compositional range of Pt1.05Mn0.90Sn1.05∼Pt0.94Mn1.12Sn0.94. These alloys in solid solution have lattice parameters of about 6.271∼6.249 Å at room temperatures, saturation magnetizations of 45.0∼55.0 emu/g at absolute zero, magnetic moment of 3.25∼3.37 μB per Mn atom at absolute zero, and the Curie temperatures of 313∼365°K.
The magnetic susceptibility of these alloys has been found to satisfy the Curie-Weiss law above the Curie temperature.
