Ferromagnetic and Spin-Wave Resonance in Exchange-Coupled NiFe/Ag/NiFe Three-Layer Structures
FMR and SWR spectra of exchange-coupled structures NiFe/Ag/NiFe have been investigated. We revealed that the optical satellites of the exchange spin-wave modes are characterized not by the standard Kittel-dependence but rather by their own resonance field dependence on the mode number: Hropt(n)~n5/2.
