Experimental study demonstrates magnetic domain formation in copper-doped iron alloys, suggesting pulse parameters tune magnetic performance.
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.
