Influence of the $\Delta E$ effect on the field dependence of the magnetoelectric effect in the region of electromechanical resonance

The influence of the $\Delta E$ effect on the field dependence of the resonant magnetoelectric effect in bulk composite materials with a composition of ferrite nickel spinel–lead zirconate titanate has been investigated in the electromechanical resonance region. It has been shown that the field dependence of the effect is determined not only by the magnetic-field dependence of the piezomagnetic coefficient, but also by the field dependence of the Young modulus. The dependence of the resonance frequency of the effect on the bias field has been analyzed.
