We have analyzed the crystallization effects on the Hall resistivity and magnetoresistance in two different sets of Go-based amorphous glasses having a similar composition and commercially known as Metglas and Vitrovac. The behaviours of the Hall constants R o and R s show that the mobility μ of the conduction electrons of the crystallized phase is improved in comparison with that of the amorphous phase and at the same time the scattering effects are reduced. Moreover, the ferromagnetic anisotropic resistivity (FAR) increases with the Co percent content and decreases with resistivity while this does not occur in crystallized samples. In the latter, the longitudinal and transverse variations of resistivity with applied magnetic field are equivalent, but the values of the FAR are much higher than those of the amorphous state. The behaviour of the nanostructured samples is quite similar to that of the amorphous state.
