Abstract

Results concerning the Hall resistivity, spontaneous Hall coefficient, longitudinal and transversal magnetoresistance and ferromagnetic anisotropic resistivity for as-cast and thermally treated Co65.75Fe4.5Si12.25 B15Mo2.5 amorphous ribbons are presented. The obtained results show a strong dependence of the electrical properties of the samples on the thermal treatment. In the nanocrystallized samples the value of ferromagnetic anisotropic resistivity (+1.65x10-4) is quite similar to that of the amorphous samples (+1.17x10-4). In the crystallized state the value of ferromagnetic anisotropic resistivity increases up to +17.93x10-4..
