Abstract :
The spectral characteristics of the hybrid spin-electromagnetic waves in multiferroic layered structure magnonic crystal (MC)-ferroelectric were theoretically and experimentally investigated. The main features of the bandgaps formation in such a structure were compared with the case of a single MC. The possibility of the bandgap characteristics control with varying electric field is demonstrated.
