Abstract

Giant sharp converse magnetoelectric (CME) coefficient of 11.9 GV is obtained in a heterostructure formed by combining a Rosen-type 0.7Pb (Mg1/3Nb2/3) O3-0.3PbTiO3(PMN-PT) piezoelectric single-crystal transformer with a CME laminated composite of a length-magnetized Tb0.3Dy0.7Fe1.92(Terfenol-D) magnetostrictive alloy plate sandwiched between two thickness-polarized, electroparallel-connected PMN-PT piezoelectric single-crystal plates. The observed giant sharp CME is found to originate from the step-up voltage-gain effect in the transformer and the resonance CME effect in the laminated composite. This heterostructure has promising applications in electrically controlled magnetic memory devices.
