Abstract: The high-frequency spin excitations in the Cr$_{1/3}$NbS$_2$ helical magnet have been investigated. The contributions of the uniform and Goldstone modes of the spin precession have been determined. It has been shown that the resonant field of the uniform mode is determined by the uniaxial magnetocrystalline anisotropy. Final values of the energy and the resonant field of the Goldstone mode are determined by the sixth-order magnetocrystalline anisotropy in the basal plane.
