Abstract :
Propagation of spin-electromagnetic waves in thin-film multilayered multiferroic structures have been investigated both experimentally and theoretically. The thin-film structure was composed of a ferrite film, a ferroelectric film, and a slot transmission line. It was shown that the spectrum of the spin-electromagnetic wave was formed by hybridization of the spin wave in the ferrite film with the electromagnetic wave in the slot-line.
