In this paper, we discuss how the material parameters of piezoelectric phase affect the magnetoelectric properties of the laminate composite especially focusing on the role of loss factors and electromechanical resonance of piezoelectric phase. By analyzing experimental results of magnetoelectric laminate composite consisting of Pb(Zr,Ti)O3-based piezoelectric layer and Metglas ferromagnetic layers, we demonstrate that the losses of piezoelectric materials play an important role in controlling the magnetoelectric sensitivity of the laminate composite. Further, we show that direct magnetoelectric effect is maximized at anti-resonance frequency while the converse magnetoelectric effect is maximized at resonance frequency of the laminate composite.
