Abstract
An expression for the description of the frequency-dependent magnetoelectric response in hybrid magnetostrictive-piezoelectric multiferroic composites is presented by using constitutive and motion equations. The calculations show that the values of the magnetoelectric voltage coefficient of the composites in the region of an electromechanical resonance sharply increase and exceed a low-frequency value by more than two orders of magnitude, which is in reasonable agreement with recent experimental data. The enhanced magnetoelectric response at the electromechanical resonance is dependent on the interface losses.Keywords
