Curie Temperature of Amorphous Ferromagnets of Type Fe-TM-M

The theoretical Heisenberg model of an amorphous ferromagnet having two magnetic com paonents iu the Bethe-Peierls-Weiss approximation was apapalied to study the concentration dependence of the Curie temperature of the Fe-TM-M alloys (TM -transition metal, Μ -metalloid).The analysis of the experimental data in comparison with the model calculations was performed.
