Abstract
The effect of fluctuating parameters of ferromagnets on non-uniform ferromagnetic resonance (NUFMR) is studied by Green's function method. Two different cases of anisotropy constant inhomogeneities or magnetization fluctuations are considered. For both cases the modified dispersion relation for NUFMR in Bourret's approximation is found. It is shown that inhomogeneities could be studied by means of dependence of damping factor for average field on wave vector. The equation of radiation transfer is investigated. The dependence of different modes intensity on the wave vector and intensity of exitation mode is obtained.
