We report an extrinsic magnetoelectric effect in composite laminates made by sandwiching one thickness-polarized 0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3(PMN-PT) piezoelectric single crystal plate between two length-magnetized, polymer-based pseudo-1-3 (Tb0.3Dy0.7)0.5Pr0.5Fe1.55magnetostrictive composite plates. The laminates exhibit large magnetoelectric voltage coefficients (αV) of ∼0.17 V/Oe with a flat response for frequencies in excess of 40 kHz and of ∼2.97 V/Oe at the natural resonance frequency of ∼65 kHz. The distinct advantages of the laminates include high magnetic field sensitivity, low Joule heating loss, wide operating bandwidth, and low cost.
