Abstract
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.
