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

Magnetic properties of amorphous alloys of the type Fe_{80-x}TM_{x}B_{20} (0 ≤ x ≤ 20 at.%, TM = Ni, Co, Mn, Cr, V, Ti) are presented and analyzed. The basis of our research work was the Mössbauer measurements, magnetic saturation measurements, derivative thermo-magnetogravimetry and differential thermal analysis measurements. The magnetic moments are discussed in terms of Friedel's virtual-bound-state model for light TM impurities in strong ferromagnets. Some conclusions about the electronic structure are presented.
