Abstract
The magnetoelectric (ME) effect in ferrite-piezoelectric bilayers has been theoretically studied at coinciding frequencies of the electromechanical resonance in the electric subsystem and ferromagnetic resonance in tangentially magnetized ferrite. Giant values of the ME voltage coefficient (50–70 V/A at 5 GHz) are predicted for the YIG-PZT system. In contrast to the case of a normally magnetized plate, the magnetoacoustic resonance in a tangentially magnetized sample takes place at a lower value of the magnetic bias field and a smaller ferrite layer thickness. This effect can be used for the development of multifunctional ME nanosensors and transducers operating in the microwave range.
