摘要：
Magnetoelectric resonance behavior of a simple, bilayered structure of Pb(Zr,Ti)O-3 ceramic chip and (Tb,Dy)Fe-2/epoxy mixture layer is investigated. Our results show that there occur three kinds of resonance, which are attributed to the first-order flexural, second-order flexural, and radial resonance modes, respectively. The measured phase spectra show a significant phase change around each resonance frequency. The thinner PZT chip is benefit for higher flexural resonance magnetoelectric effect. The magnetoelectric effects measured under open and short electric boundary conditions show different behaviors. This simple bilayered structure exhibits a large charge output of about 300 pC/Oe at the resonance frequency. (c) 2007 American Institute of Physics.
