Abstract
The spin wave resonance (SWR) spectrum of a structure with two differe nt magnetic layers was investigated by means of an experimental techni que based on the effect of resonant interaction of magnetostatic Damon -Eshbach and exchange waves. We show that in the presence of exchange coupling, the frequency position and intensity of SWR lines oscillate during magnetic field variation. These oscillations are due to the 're pulsion' effect of the SWR lines, which takes place at frequencies cor responding to the coincidence of single-layer spectrum frequencies.
