The theoretical Heisenberg model of an amorphous ferromagnet having tw
o magnetic components in the Bethe-Peierls-Weiss approximation was app
lied to study tile concentration dependence of the Curie temperature o
f the Fe-TM-M alloys (TM -- transition metal, M -- metalloid). The ana
lysis of the experimental data in comparison with the model calculatio
ns was performed.
