The present investigation focuses on magnetoelectric interactions in ferrite-piezoelectric
bilayers in the ferromagnetic resonance (FMR) region. A dc electric field applied
perpendicular to the sample plane gives rise to an in-plane strain that is transferred to the
ferrite and produces a uniaxial thickness-dependent magnetic anisotropy. Expressions for
microwave magnetic susceptibility are obtained taking into account the effects of flexural
deformations. The results are applied to the specific case of yttrium iron garnet (YIG)/lead …
