Abstract
The dynamic magnetic susceptibility (χac) 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 χac the Curie temperatures of these alloys are determined. It is established that tin-doped alloys have higher Curie temperatures as compared to Gd5Si2Ge2 (ΔT C ≈ 15 K).
