Abstract

A magnetoelectric composite consisting of a multilayer Pb(Zr,Ti)O-3 piezoelectric (d(33)) 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 16.4 nC/Oe (or 3.6x10(-6) C/m(2) Oe) were found at quasistatic frequencies and 123 nC/Oe (or 2.8x10(-5) C/m(2) Oe) under resonance drive, which are 100-1000 times higher than that previously reported for other ME laminates.
