The magnetoelectric properties of lead zirconate titanate/terfenol-D/PVDF laminate composites

Lead zirconate titanate (PZT-5)/Tb0.28Dy0.72Fe1.95 (Terfenol-D)/poly vinylidene fluoride (PVDF) laminate composites were prepared using stacking and heat-pressing together one Terfenol-D+PVDF disk and two layers of PZT+PVDF. The dependence of the magnetoelectric conversion coefficient (dE/dH) of these composites on the value of applied dc magnetic field, thickness of layers and frequency of the ac magnetic field has been studied systematically. The results indicate that the dE/dH can reach the maximum 126.84 mV/cm.Oe when the layers thickness ratio of PZT+PVDF to Terfenol-D+PVDF is 0.375/1.0.
