Ya. Filimonov et al., EVIDENCE OF THE EXCHANGE COUPLING EFFECT IN THE SPIN-WAVE SPECTRUM OFA STRUCTURE WITH 2 DIFFERENT MAGNETIC LAYERS, Journal of magnetism and magnetic materials, 131(1-2), 1994, pp. 235-241
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.
