摘要：

The regularities of the influence on the magnetic properties of temperature and the strength of the longitudinal magnetic field, which is much less than the saturation field, during annealing of an amorphous soft magnetic alloy based on Fe were studied. The possibility of efficiency of such treatment in comparison with traditional annealing without a field is demonstrated. It is shown that the change in magnetic properties during annealing is not related to the crystallization processes of the amorphous alloy. Annealing in unsaturated field at a temperature of 410 °C showed the greatest efficiency in achieving the highest soft magnetic properties of the alloy (low coercive force Hc = 3 A/m, high maximum and low-field permeability µmax = 101,000, µ2 = 5019) among short-term treatments with a holding time of 10 min. The results obtained are discussed taking into account the processes of magnetic anisotropy induction and stress relaxation in the alloy.
