摘要：
The dynamics of a 180° domain wall in a magnet with two-dimensional inhomogeneities of the parameters of magnetic anisotropy and the conditions of excitation of nonlinear magnetization waves have been investigated using numerical methods. Three types of localized magnetic inhomogeneities that appear in the region of anisotropy inhomogeneities have been revealed, namely, a pulson, a pulson transforming into a 2D soliton, and a 2D soliton. Regions of the values of the parameters that describe the magnetic-anisotropy inhomogeneities, which determine the existence of each of these inhomogeneities, have been found.
