Giant magnetoelectric effect in Pb(Zr,Ti)O3-bimorph/NdFeB laminate device

Abstract

A Pb(Zr,Ti)O3-bimorph/NdFeB laminate device has a giant magnetoelectric (ME) effect. Our results reveal a giant ME coefficient of 16V∕cmOe or 62nC∕cmOe at a low (subresonant) frequency of 10Hz, and one of 250V∕cmOe or 960nC∕cmOe at a first order resonant bending mode frequency of ∼60Hz. The findings show a simple means by which to achieve magnetoelectric effects, without the use of magnetostrictive material.

Giant magnetoelectric torque effect and multicoupling in two phases ferromagnetic/piezoelectric system

“…Some people then tried to find new giant MS materials, new forming technologies, and some began to seek new mechanisms. 24,25 Although the ME effect could appear in the ferromagnetic (FM)/PE two phase system from the symmetry point of view, giant ME contribution of the two phase system are always accredited to the MS-PE interaction. 1,23,26 This might comes from the intuitive understanding of the intimate contact coupling of the MS and PE phase, however, another coupling has been overlooked for years.…”

Resonance magnetoelectric effect in Ni/Pb(Zr,Ti)O3/Terfenol-D trilayered composites with different mechanical boundary conditions

“…Therefore, how to control the resonance frequency is an important research topic for the laminated ME composites. 16,17 In this Letter, the ME effect in Ni/PZT/ Terfenol-D trilayered composites with various mechanical boundary conditions was reported. ME composites were made up of negative magnetostrictive/piezoelectric/positive magnetostrictive layers by electroless deposition and silver epoxy bonding.…”

ELECTRICAL PROPERTIES OF FERROELECTRIC BaTiO3-on-Ni MULTILAYER CAPACITORS FOR ROOM-TEMPERATURE MAGNETOELECTRIC DETECTORS

“…The use of composite multilayers for weak-field magnetic detectors has recently emphasized sandwiches of magnetostrictive materials such as terphenyl-d with piezoelectrics such as lead zirconate-titanate (PZT), as developed by the groups of Srinavasan in Michigan [1][2][3][4][5][6], Viehland in Virginia [7][8][9][10] and Fetisov in Moscow [11][12][13][14]. A cheaper alternative reported by Israel et al [15] is the multilayer capacitor made of BaTiO 3 with Ni electrodes.…”
