摘要：

In this work, the particularities of the spin wave (SW) excitations in corrugated yttrium-iron garnet (YIG) films with a thickness of 0.2 μm and a corrugation period of 20 μm were studied by micromagnetic simulations. Strong influence of the corrugation depth, changing from 0 to 0.5 μm, on SW dispersion, transmission and eigenmode spectrum was shown. Formation of a bandgap resulting from the spin-wave resonances in the sidewalls of the corrugated YIG film was discovered in the SW dispersion and transmission spectrum in addition to the Bragg bandgaps and dipole-exchange resonance. © 2021 Elsevier B.V.
