摘要：

The dynamic piezoelectric response of ferroelectric ceramics is comprised of both intrinsic (piezoelectric lattice strain) and extrinsic (non-180 degrees domain wall motion) components. Here the authors report direct measurements of non-180 degrees domain wall motion in ceramic lead zirconate titanate during application of subcoercive cyclic driving electric fields using an in situ stroboscopic neutron diffraction technique. During unipolar cycling at 1 Hz and half of the coercive field, non-180 degrees domain switching gives rise to approximately 34% of the measured d(33) coefficient of 400 pm/V.
