摘要：

The propagation of spin waves in the presence of a single skyrmion was considered. It was found that short-wavelength spin waves are hardly scattered, and that the main effect consists in an additional rotation of the spin deviation around the unperturbed spin direction in skyrmions. A special branch of collective excitations was found corresponding to oscillations of the skyrmion core size.
