Magnetoelectric resonant characteristics in Pb(Zr,Ti)O3/Terfenol-D laminate composites

Abstract

Magnetoelectric (ME) characteristics in a simple Pb(Zr,Ti)O3/Terfenol-D laminate composite are investigated. Both magnetomechanical and electromechanical resonances (EMRs) can enhance ME coupling and the latter plays a more important role. The phase spectra show a significant phase shift of 0.75π–π around each EMR frequency and a clear phase bouncing around each magnetomechanical resonance frequency. The distributions of the electric-field-induced magnetization (EIM) express different manners in longitudinal and transverse directions, which are attributed to the magnetized directions and the resonant modes. When the driving electric field frequency is near one of the integer EMR frequencies, multiple resonance EIMs are observed.
