摘要：

The present paper focuses on magnetoelectric (ME) interactions under ferromagnetic resonance (FMR) in a bilayer of a ferrite and a piezoelectric. Applying a dc electric field perpendicular to the sample plane induces a uniaxial magnetic anisotropy. The effects of flexural deformation and substrate clamping have been considered in determining the electric field induced FMR line shift. The obtained model is applied to a specific case of yttrium iron garnet/lead magnesium niobate-lead titanate. Our studies indicate that flexural deformation gives rise to a decrease in the strength of ME interaction for a free standing bilayer. The substrate thickness dependence of FMR line shift reveals a maximum for the substrate thickness that is approximately equal to that of the bilayer.
