• 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 stoichiometic 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(Sl_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 6.201Å at room temperature, ferromagnetic Curie temperatures of 360° and 582°K, numbers of Bohr magnetons of 3.65 and 4.14μ_B/mol at 0°K and the internal magnetic field of 204.5 and 220.2kOe at Mn^<55> nucleus at 77°K, respectively.
