Theoretically investigated the origin and evolution of the three types of dynamic magnetic inhomogeneities (a breather, breather transforming into a soliton, and a soliton), appearing in a flat layer of the parameters of magnetic anisotropy and exchange interaction, different from the parameters in the main area of the infinite in a ferromagnetic after the passage of the 180-degree domain wall. Found the values of parameters, which determine the possibility of the existence of each of the magnetic inhomogeneities. For the magnetic inhomogeneities of the types damped quiescent breather and soliton obtained dependence of the amplitude and frequency of oscillations of the parameters of the defect.
