Effect of heat treatment on the shape of the hyperfi ne fi eld induction distributions and magnetic properties of amorphous

Thermal treatment, undertaken at just below the crystallization temperature, has led to nanocrystalliza- tion and has had a signifi cant impact on the shape of the hyperfi ne fi eld induction distributions of Fe62Co10Y8B20 alloy and on its soft magnetic properties. In the amorphous ferromagnetic alloys, it is possible to indirectly deter- mine the effect of the structure stresses, resulting from the presence of structural defects, on the soft magnetic properties of these materials. It has been found that a change in the parameters associated with the presence of structural defects affects the shape of the hyperfi ne fi eld distributions of 57 Fe.
