Physical Mechanisms of Reverse Magnetization Jumps and Improvement of the Functional Characteristics of Ferromagnetics

Resumo

The physical mechanism of reverse magnetization jumps, which are induced by the minimization of the total energy of a growing magnetic phase in the process of magnetization of a ferromagnetic, is revealed. The ways toward enhancing the magnetic induction and suppressing the magnetostriction and magnetic losses in Fe–3% Si alloys through adjustment of the parameters of magnetization jumps are outlined. The effective refinement of the structure of magnetic materials leads to a considerable improvement in the magnetic characteristics.
