In this study, the temperature dependences of the electrical resistivity (ρ) and the Hall coefficient (RH) of amorphous alloys of the Fe85−хCrхB15 (x = 8, 10, 12, 15) system based on 3d elements are experimentally investigated. The alloys are obtained from the liquid state by the melt-spinning (ultrarapid quenching) technique. Measurements are carried out in the temperature range 300−773 K using the Van der Pauw method. As established, the ferromagnetic–paramagnetic phase-transition temperature of the samples is fully correlated with the temperature dependences of both the Hall coefficient and the electrical resistivity, whereas the amorphous–crystalline phase-transition temperature varies depending on the iron content in the samples. The results of the mutual and temperature dependences of the electrical and galvanomagnetic properties of the samples are analysed. As a result of a comprehensive experimental study of the electrical and galvanomagnetic properties of amorphous Fe−Cr−B alloys, it becomes possible to estimate the effective spin–orbit interaction parameter for these samples.

Key words: amorphous alloy, Curie temperature, crystallization temperature, Hall coefficient, electrical resistivity, effective spin–orbit interaction parameter.
