Abstract
The manuscript discusses a theoretical model that predicts a giant magnetoelectric (ME) coupling in laminates of ferrite and piezoelectric bimorph at the coincidence of electromechanical resonance for the electrical subsystem and ferromagnetic resonance for the ferrite. In such structures, the ME interaction is a result of mechanical strain. Using the piezoelectric bimorph gives rise to the excitation of high-order harmonic modes that are suppressed in ferrite-piezoelectric bilayers. ME coefficients, on the order of 590 V/A at 4.96 GHz, is predicted for the third resonance mode in laminate of yttrium-iron garnet and langatate bimorph. The phenomenon can be used for the realization of microwave sensors based on ME interaction.
