Abstract

We present a theory for the resonance enhancement of ME interactions at frequencies corresponding to electromechanical resonance (EMR). Frequency dependence of ME voltage coefficients are obtained using the simultaneous solution of electrostatic, magnetostatic and elasto-dynamic equations. The ME voltage coefficients are estimated from known material parameters (piezoelectric coupling, magnetostriction, elastic constants, etc.) of composite components. It is shown that the resonance enhancement of ME interactions is observed at frequencies corresponding to EMR and ME coupling in the EMR region exceeds the low-frequency value by more than an order of magnitude. It was found that the peak transverse ME coefficient at EMR is larger than the longitudinal one. The results of calculations obtained for a nickel-ferrite spinel–PZT composite are in good agreement with the experimental data.
