摘要
We propose an analytic model for the quantitative assessment of a volume jump of domain walls, caused by the Barkhausen effect, under the action of a magnetic field accompanied by magnetoelastic acoustic emission. Dependences for the evaluation of its amplitudes are constructed. Initial data for the calculation of displacements with the proposed model are obtained. It is shown that the method of magnetoelastic acoustic emission is sensitive to the reconstruction of the domain structure of ferromagnets.
