Effect of an external magnetic field on the dynamics of the nucleus of a new phase near the first-order phase transition in magnetics with defects

Abstract

The evolution of the nucleus of a new phase near the point of a spin-reorientation first-order phase transition in its magnetics in an external magnetic field is investigated. The effect of the external field and one-dimensional magnetic anisotropy defects on the dynamics of such a nucleus is investigated. Critical fields that promote remagnetization of the sample are noted and evaluated.
