NONUNIFORM NONLINEAR OSCILLATIONS OF A DOMAIN-WALL IN UNIAXIAL FERROMAGNET

The nonlinear small amplitude excitations of a domain wall (DW) in the ferromagnet with high uniaxial anisotropy are investigated using reduced magnetodynamic equations. The ''life-time'' of soliton-like oscillations of DW in the nondissipative media is defined. The conditions of direct and parametric stabilization of self-localized DW oscillations by alternating magnetic fields are analyzed in the presence of dissipation.
