Abstract

Magnetoelectric (ME) laminate composite consisting of optimal crystal cut thickness-polarized piezoelectric 0.7Pb (Mg13 Nb23) O3 -0.3PbTi O3 (PMN-PT) single crystal and the length-magnetized magnetostrictive Tb0.3 Dy0.7 Fe1.92 (Terfenol-D) alloy has been fabricated. The cut optimization of PMN-PT crystal greatly enhances the longitudinally magnetized-transversely polarized (L-T) mode ME effect, which has a superior ME voltage coefficient αE of ∼3.02 Vcm Oe in low frequency band. Near the resonance frequency of 95 kHz, the coefficient dramatically increases and reaches the maximized value of 33.2 Vcm Oe, which is almost two times larger than the previously reported 〈001〉-oriented PMN-PT crystal based L-T mode laminate composite.
