The effect of magnetic pulse treatment on the magnetic structure of foil made of amorphous alloy Fe(SiBNb) with the addition of 1% copper was studied. The foil was obtained by the method of ultra-fast cooling during melt spraying on a rapidly rotating copper drum. It was found that because of the action of pulses of a weak magnetic field, a domain structure appears in the material under study. The nature of the domain structure and the magnetic characteristics of the foil depend on the parameters of magnetic pulse treatment.
Kaminskaya et al. (Wed,) studied this question.
