Abstract

The authors study the effect magnetic pulse treatment has on the magnetic structure of foil made of amorphous alloy Fe73(SiBNb)27 with additions of 1% copper. The foil is obtained via ultra-fast cooling while spraying the melt on a rapidly rotating copper drum. It is found that a domain structure appears in the material, due to the action of pulses of a weak magnetic field. The nature of the domain structure and the magnetic characteristics of the foil depend on the parameters of magnetic pulse treatment.
