摘要：

Two PbZr(1-x)TixO(3) (PZT) single crystals with x approximate to 0.45 and 0.42 near the morphotropic phase boundary were studied by Brillouin light scattering, giving rise to the first single-crystal elastic data which were discussed in terms of the correlation between the acoustic anomalies and the phase transition sequence. The ferroelectric phase transition of PZT with x approximate to 0.45 was second order (or very close to the second order) which accompanied very large polarization fluctuations resulting in the formation of strong central peaks. A revised phase diagram of PZT was suggested including refinement of the tilt phase boundary and a possible existence of tricritical point. (C) 2012 American Institute of Physics.
