Abstract
In this work, we have carried out a numerical integration of Landau-Lifshitz equations for a non-dissipative highly anisotropic uniaxial ferromagnet in the region of the nonparametric threshold radiation of spin waves by a domain wall (DW) moving in the precessional dynamical mode in a strong dc field. The deviation of the calculated values of the forward velocity of a DW is different from zero because of the backward reaction of the field of radiation on it from the known analytical results increases with decreasing constant of uniaxial anisotropy and with approaching the acting field the threshold value. Special attention is given to the asymmetry of the field of radiation relative to the DW plane depending on the direction of the DW velocity.
