A high‐frequency branch of the spectrum of excitations of a domain wall in uniaxial ferromagnetics, discovered by Gilinskii, is studied. A dispersion law for all directions of the wave propagation is derived from the Landau‐Lifshitz equation in magnetostatic approximation. Results are obtained in the long wave limit. A comparison of the theoretical and numerical results is presented.
