Investigation of the Hall effect in low magnetostrictive cobalt based amorphous ribbons

Results concerning the Hall voltage UH and spontaneous Hall coefficient Rs dependence on the external magnetic induction and heat treatment conditions for Co68.25Fe4.5Si12.5B15 amorphous ribbons tested in the as-cast state and after stress current annealing are presented. An n-type conductivity was observed for this kind of material. The obtained results show as strong dependence of the electrical properties of the samples on the current density annealing.
