摘要：
FMR and SWR spectra of exchange-coupled structures NiFe/Cu/NiFe, NiFe/Ag/NiFe and NiFe/DyCo/NiFe have been investigated. We revealed that the optical satellites of the exchange spin-wave modes are characterized not by the standard Kittle-dependence but by their own resonance field dependence on the mode number: H-r(opt)(n) similar to n(5/2).
