摘要：

A two-phase magnetoelectric (ME) parallel sandwich was developed by bonding two longitudinally magnetized Terfenol-D/epoxy pseudo-1-3 magnetostrictive composite plates on two longitudinally polarized PZT/epoxy 2-2 piezoelectric composite plates combined longitudinally as a single plate and with their polarization directions arranged in reverse directions. A significantly large ME voltage sensitivity (MEV) of 3.1 V/Oe was observed at the resonance frequency of 42.8 kHz under a relatively low bias field of 0.8 kOe. This resonance MEV was similar to 35 times larger than its nonresonance values, showing great promise of using the proposed sandwich in ME conversion devices. (C) 2006 Elsevier B. V.
