Abstract:
Laminar piezoelectric-magnetostrictive composites using piezoelectric lead
zirconate titanate ceramics and the giant magnetostrictive rare-earth-iron alloy
Terfenol-D were prepared by epoxy bonding. The direct and converse
magnetoelectric (ME) effects at and off the mechanical resonant frequency were
characterized and compared to the theoretical modelling. The mechanical resonant
frequency of the composites depended on the sample orientation and the magnetic
DC bias field. In the longitudinal configuration, the resonant frequency shifted
down monotonically with the increasing bias field. When the sample was in the
transverse configuration, the resonant frequency decreased with the increasing
field at first. However, at higher bias, it shifted up with the increasing bias.
A phenomenological model based on the à  E effect of magnetostrictive materials
is proposed to explain the observed phenomena
