The converse magnetoelectric effect (CME) response of a Pb(Zr0.52Ti0.48)O3 (PZT)/ Tb0.30Dy0.7Fe2 (Terfenol-D)/PZT laminate to applied DC voltage bias has been investigated. Experimental data demonstrates that the CME coefficient αCME is highly dependent on applied voltage bias. The voltage bias is shown to increase the piezomagnetic coefficient δλ/δB of the Terfenol-D and by extension the αCME, however an optimal αCME has yet to be identified. The ME laminate exhibits considerable gains in αCME (up to 100%) due in part to the improved magnetostrictive response of Terfenol-D under piezoelectric-induced mechanical stress.
