The paper considers the change in the spectrum of ferromagnetic resonance in ferrite-piezoelectric layered structures in an external electric field. The induced magnetic anisotropy through the magnetoelastic interaction is generally non-uniform in thickness due to the presence of bending deformations. As a result, the applied electric field leads to a shift and broadening of the magnetic resonance line, which are determined by the composition and geometric dimensions of the structure layers. The paper presents a theoretical modeling of the magnetic resonance line broadening when additional buffer layers are inserted between the ferrite and piezoelectric layers to reduce the effect of a high-permittivity piezoelectric on the microwave field structure in the ferrite. The simulation results are considered on the example of layered structures of the composition of iron-yttrium garnet - lead titanate-zirconate. It is shown that at certain thicknesses of the magnetic and piezoelectric layers, the broadening of the magnetic resonance line as a function of the thickness of the buffer layer has a maximum. The results can be used in frequency-selective microwave devices with electrically tunable range.
