摘要：
The dynamic magnetic susceptibility (chi(ac)) of magnetically ordered Gd5Si2-xGe2-xSn2x compounds with the partial substitution for silicon and germanium atoms by isovalent tin atoms (2x = 0 - 0.1) has been investigated experimentally. From the temperature dependence of chi(ac) the Curie temperatures of these alloys are determined. It is established that tin-doped alloys have higher Curie temperatures as compared to Gd5Si2Ge2 (Delta T (C) a parts per thousand 15 K).
