Salient features of the electrical resistivity and magnetoresistance of the Fe-, Co- and Ni-based amorphous metallic alloys are considered. The analysis of theoretical approaches to the description of scattering mechanisms in these systems is performed. Phenomenological model of the field dependences of magnetoresistance of ferromagnetic amorphous alloys is developed. The parameters of such a model are validated, and the possibility of its application to the determination of key parameters of amorphous alloys is proved.
Keywords: amorphous metallic alloys, transition metals, electrical conductivity, magnetoresistance, domain structure, anisotropy field.
