Abstract

Multicoupled magnetoelectric (ME) effect originated from the interaction of magnetostriction, magnetic-torque and piezoelectricity was proposed. A three-phase Tb_1-xDy_xFe₂/Pb(Zr_1-xTi_x)O₃/NdFeB bimorph laminates with this mechanism was designed and investigated. We found that the magnetic DC bias could tune the multicoupling and lead to an enhancement or attenuation in ME effect. The ME voltage coefficient could be enhanced by a factor of 2.6 times (or 2.2 times for practical device construction) that of a conventional bimorph ME device. A simple and effective mode analysis method was introduced for the multicoupled device design. This research has provided a sight of designing better ME devices with the multicoupling consideration.
