摘要：

In this work we investigate numerically the nonlinear dynamics of the interaction of a single-domain wall with the region of inhomogeneity of the magnetic-anisotropy constant (of rectangular or gaussian shape) in ferromagnetic. The dependence of the minimum velocity necessary for passing through the inhomogeneous region is obtained as the function of the material parameters and parameters of the magnetic breather, which is excited in the region of the defect. Comparison with the known analytical and numerical results is made.
