用X射线衍射、磁分析和核磁共振等方法研究了Pt-Mn-Sn和Pt-Mn-Sb合金的晶体结构和磁性能。结果表明，化学计量比为PtMnSn和PtMnSb的合金均为铁磁性，前者为CaF 2（Cl）型结构，后者为MgAgAs（Cl B）型有序结构。Pt 1.01 Mn 0.99 Sn 1.00和Pt 1.01 Mn 1.00 Sn 1.00合金在室温下的晶格常数分别为6.263和6.201，铁磁居里温度分别为360°和582°K，在0°K时，Bohr磁子数分别为3.65和4.14 µ B /mol，在77°K时，Mn 55核的内磁场分别为204.5和220.2 kOe。
Crystal structures and magnetic properties of Pt-Mn-Sn and Pt-Mn-Sb alloys have been investigated by means of X-ray analysis, magnetic analysis and nuclear magnetic resonance. It is found that the alloys with the stoichiometric compositions PtMnSn and PtMnSb are ferromagnetic and that the former has a structure of the CaF 2 (Cl) type while the latter an ordered structure of the MgAgAs (Cl b ) type. Pt 1.01 Mn 0.99 Sn 1.00 and Pt 1.01 Mn 1.00 Sn 1.00 alloys have lattice parameters of 6.263 and 6.201 A at room temperature, ferromagnetic Curie temperatures of 360° and 582°K, numbers of Bohr magnetons of 3.65 and 4.14 µ B /mol at 0°K and the internal magnetic field of 204.5 and 220.2 kOe at Mn 55 nucleus at 77°K, respectively.
