Abstract:	Brillouin scattering from relaxor ferroelectric Pb(Zn1/3Nb2/3)O3 has been measured between 296 and 780 K. Heating of the virgin Pb(Zn1/3Nb2/3)O3 crystal produced results that are different from those of subsequent heating or cooling processes. An unusually broad softening of the longitudinal acoustic-mode frequency, due to the diffuse ferroelectric-phase transition, is observed. The attendant phonon damping is attributed to order-parameter fluctuations. A huge temperature hysteresis, which eluded observation by other techniques, has been found. © 2001 American Institute of Physics.
