Magnetoelectric laminate composites of piezoelectric-magnetostrictive materials were investigated. The composites were prepared by stacking and bonding Pb(Zr, Ti)O-3 (PZT) and Terfenol-D disks. Experimental results indicated that the magnetoelectric voltage coefficient. dE/dH. increased with decreasing thickness and increasing piezoelectric voltage constant (g(31)) of the PZT laver. We obtained the highest magnetoelectric voltage coefficient of 4.68 V/cm . Oe at room temperature for the sample with high g(33) PZT of 0.5 mm in thickness. This value is about 36 times higher than the best reported value.
