Abstract: A combined effect of laser treatment and introduced fine-grained weakly magnetic impurity Mg–P–B defects on the magnetic structure and physical properties of anisotropic electrotechnical materials has been investigated. Specific features of changes in the type and behavior of the magnetic domain structure under different types of deformation (laser irradiation, scratching, and introduction of interstitial defects) have been revealed. The physical basis and optimum conditions of increase in thermal stability of local laser treatment zones in soft magnetic alloys have been determined. The obtained results open the prospects of decreasing magnetic losses in soft magnetic alloys and producing magnetic materials with a high level of physical and mechanical properties that are more resistant to operating conditions.

Keywords: Magnetic Loss, Laser Power Density, Closure Domain, Stripe Domain, Magnetic Domain Structure.
