We report a large voltage gain of 130, together with a high magnetoelectric voltage coefficient of 7.6 V/Oe, in a long-type heterostructure made by combining a coil-wound, length-magnetized magnetostrictive Tb0.3 Dy0.7 Fe1.92 (Terfenol-D) alloy plate and a length-polarized piezoelectric 0.7Pb (Mg1/3 Nb2/3) O3-0.3 PbTiO3 single-crystal plate along the length direction. The observed voltage gain is found to originate from the product effect of the electromagnetic induction in the coil and the resonance magnetoelectric effect in the heterostructure.
