Abstract
The dispersion relation of the spin waves in thin ferromagnetic film near the phase transition point from the homogeneous magnetization state to the domain structure has been obtained. Calculations have been carried out within the pheonomenological theory utilizing the Holstein—Primakoff expansion in the first approximation.
