Spin waves in a ferromagnet with anisotropic inhomogeneities

A spin waves damping Γ caused by the inhomogeneities of an exchange parameter described by anisotropic correlation functions is considered. The anisotropy leads to the appearance of the new dependences Γ on the wave vector k : Γ α k 4, k sol:7 2 and k 3−2 n besides well-known laws: Γ α k 5 k 5+2 n a...

Summary:A spin waves damping Γ caused by the inhomogeneities of an exchange parameter described by anisotropic correlation functions is considered. The anisotropy leads to the appearance of the new dependences Γ on the wave vector k : Γ α k 4, k sol:7 2 and k 3−2 n besides well-known laws: Γ α k 5 k 5+2 n and k 3.
