We report an extrinsic magnetoelectric effect in composite laminates made by sandwiching one thickness-polarized 0.7Pb(Mg(1/3)Nb(2/3))O(3)-0.3PbTiO(3) (PMN-PT) piezoelectric single crystal plate between two length-magnetized, polymer-based pseudo-1-3 (Tb(0.3)Dy(0.7))(0.5)Pr(0.5)Fe(1.55) magnetostrictive composite plates. The laminates exhibit large magnetoelectric voltage coefficients (alpha (V) ) of similar to 0.17 V/Oe with a flat response for frequencies in excess of 40 kHz and of similar to 2.97 V/Oe at the natural resonance frequency of similar to 65 kHz. The distinct advantages of the laminates include high magnetic field sensitivity, low Joule heating loss, wide operating bandwidth, and low cost.
