Strong magnetoelectric charge coupling in stress-biased multilayer-piezoelectric∕magnetostrictive composites Available to Purchase

A magnetoelectric composite consisting of a multilayer $Pb(Zr,Ti)O3$ piezoelectric $(d33)$ stack and a magnetostrictive (Galfenol and∕or Terfenol-D) rod assembled in a prestressed frame in a longitudinal-longitudinal configuration has been found to have a high magnetoelectric (ME) charge coupling to an applied magnetic field. Values of the ME charge coefficient as high as $16.4nC∕Oe$ (or $3.6×10−6C∕m2Oe$⁠) were found at quasistatic frequencies and $123nC∕Oe$ (or $2.8×10−5C∕m2Oe$⁠) under resonance drive, which are 100–1000 times higher than that previously reported for other ME laminates.
