Magnetic properties of Co-based and Fe-based tape amorphous alloys.

The description of the magnetic properties of amorphous alloys and comparison of the model evaluation with experimental data have been carried out in terms of the magnetic theory of disordered systems (Biryukov's theory). The hysteresis loops for a number of amorphous metallic glasses have been investigated and it also has been shown that Biryukov's hypothesis about the weak correlation between spin and electrostatic components is true for the amorphous magnetic system that permits to interpret collectively the results of different magnetometric experiments.
