INFLUENCE OF DC VOLTAGE BIAS ON THE CONVERSE MAGNETOELECTRIC EFFECT RESPONSE IN PZT/TERFENOL-D/PZT LAMINATE COMPOSITES

摘要

se of a Pb(Zr052Tio4«)03 (PZT)/ Tb(U()Dy07Fe2 (Tcrfcnol-D)/PZT laminate to applied DC voltage bias has been investigated. Experimental data demonstrates that the CME coefficient «cM/sis highly dependent on applied voltage bias. The voltage bias is shown to increase the piczomagnetic coefficient 8A78B of the Terfenol-D and by extension the aCM,,:, however an optimal aCM/.: has yet to be identified. The ME laminate exhibits considerable gains in
