Magnetoelectric effect at thickness shear mode in ferrite-piezoelectric bilayer

摘要

This manuscript discusses first observation of magnetoelectric (ME) coupling at thickness shear modes in a magnetostrictive-piezoelectric bilayer. The measured value of magnetoelectric voltage coefficient is optimized by adjusting the geometry of layers. Theoretical estimates for the bilayer of Y-cut langatate and yttrium iron garnet are in satisfactory agreement with data. The obtained results are expected to facilitate observation of enhanced ME coupling at overlapping of electromechanical and magnetic resonance due to energy transfer between spin waves and phonons.
