High-sensitivity piezoelectric perovskites for magnetoelectric composites
A highly topical set of perovskite oxides are high-sensitivity piezoelectric ones, among which Pb(Zr,Ti)O3 at the morphotropic phase boundary (MPB) between ferroelectric rhombohedral and tetragonal polymorphic phases is reckoned a case study. Piezoelectric ceramics are used in a wide range of mature, electromechanical transduction technologies like piezoelectric sensors, actuators and ultrasoun...
متن کاملEnhanced Magnetoelectric Effect in Permendur/Pb(Zr0.52Ti0.48)O3 Laminated Magnetostrictive/Piezoelectric Composite
In this work, after investigating three typical magneto-electric (ME) composites, Permendur/Pb(Zr0.52Ti0.48)O3(PZT), Metglas/PZT, and Tefenol-D/PZT, with the same dimensions and different saturation magnetostriction and magnetic permeability, the most excellent ME performance is observed in the Permendur/PZT laminates, which agrees well with the predicted results from the figure of merit. The l...
متن کاملEnhanced magnetoelectric effect in heterostructure of magnetostrictive alloy bars and piezoelectric single-crystal transformer.
We report an enhanced magnetoelectric (ME) effect in a heterostructure consisting of a long-type, longitudinally-longitudinally polarized 0.71Pb(Mg(1∕3)Nb(2∕3))O(3)-0.29PbTiO(3) (PMN-PT) piezoelectric single-crystal transformer with its input part sandwiched between two longitudinally magnetized Tb(0.3)Dy(0.7)Fe(1.92) (Terfenol-D) magnetostrictive alloy bars. The observed ME effect has two inde...
متن کاملEffect of the Magnetostrictive Layer on Magnetoelectric Properties in Lead Zirconate Titanate/Terfenol-D Laminate Composites
Magnetoelectric laminate composites of piezoelectric/magnetostrictive materials were prepared by stacking and bonding together a PZT disk and two layers of Terfenol-D disks with different directions of magnetostriction. These composites were studied to investigate (i) dependence on the magnetostriction direction of the Terfenol-D disk and (ii) dependence on the direction of the applied ac magne...
متن کاملThe magnetoelectric effect in Ni-Fe alloy/ZnO nanorod array composites.
Ni-Fe alloy/ZnO nanorod composites were fabricated and the magnetoelectric effect was demonstrated. The ZnO and Ni-Fe alloy serve as the piezoelectric phase and the magnetostrictive phase in the nanocomposite, respectively. Since the nanorod structure possesses the inherent nature of a large surface-to-volume ratio, it greatly enhances the interplay between the piezoelectric and magnetostrictiv...
