Abstract

Magnetoelectric (ME) composites have demonstrated high sensitivity for magnetic field sensor applications. Here, we report a ME laminate heterostructure consisting of magnetostrictive Tb_0.3Dy_0.7Fe_1.92 (Terfenol-D) alloy and piezoelectric polyvinylidene fluoride (PVDF) layers, both operated in shear mode. We show that the shear mode ME sensor exhibits a marked improved ME effect compared with the traditional ME composites operated in longitudinal and transverse piezoelectric and magnetostrictive modes using the same materials. A giant ME coefficient of 7.93 V/(cm·Oe) is obtained under a DC magnetic bias of 2300 Oe. The improved ME coefficient derives from the shear-mode heterostructure design, which allows both the Terfenol-D and PVDF to operate in shear mode that has maximum magnetoelectrical coupling coefficient.
