| Abstract: | The results of magnetic measurements performed on 20Fe2O3803B2O3(1?χ)PbOχAs2O3] glasses, in the temperature range 4.2 to 300 K are reported. By decreasing the temperature a downward curvature of reciprocal susceptibility is observed for T<50 K. The composition dependence of the paramagnetic Curie temperatures and Curie constants is discussed. |
