Abstract
The coherent potential approximation method is applied to spin wave re sonance in thin ferromagnetic films. The approach takes into account a natural disorder connected with different states of spin components. The resonance spectra with a finite line-width are calculated for the b.c.c. (100) film and S = 1/2. The results obtained show that the half -widths of the surface as well as the volume peaks depend on the surfa ce anisotropy parameter.
