Abstract

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 layer. 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.
