Abstract

We report the correlation between intensive and extensive losses in piezoelectric materials with the frequency dependent response of layered magnetoelectric (ME) composites. Three different piezoelectric compositions were synthesized to achieve varying loss characteristics allowing a systematic interpretation of changes in ME coupling in terms of loss components. We clearly demonstrate that intensive dielectric and piezoelectric loss play an important role in controlling the ME sensitivity of layered composites in sub-resonance low frequency range while extensive mechanical loss is dominant factor at resonance condition. Further, the maximum in ME response is obtained at antiresonance frequency of piezoelectrics.
