Abstract

The magnetoelectric effect of a laminate composite made by sandwiching a Rosen-type Pb(Mg1/3Nb2/3)O3-PbTiO3(PMN-PT) single crystal transformer between two length-magnetized magnetostrictive Tb0.3Dy0.7Fe1.92(Terfenol-D) alloy plates has been investigated. An additional giant sharp longitudinal-longitudinal (L-L) mode resonant magnetoelectric voltage coefficient of 15.6 V Oe-1due to the transformer voltage gain effect was observed besides the longitudinal-transverse (L-T) mode magnetoelectric voltage coefficient of 4.0 V Oe-1. Moreover, our novel dual-mode (L-L and L-T) laminate can provide two independent output ports, which makes the composite a promising material for multifunctional application in magnetic sensors and magnetoelectric transducers.
