Abstract
A spin waves damping GAMMA caused by the inhomogeneities of an exchang e parameter described by anisotropic correlation functions is consider ed. The anisotropy leads to the appearance of the new dependences GAMM A on the wave vector k: GAMMA is-proportional-to k4, k7/2 and k3-2n be sides well-known laws: GAMMA is-proportional-to k5, k5+2n and k3.
