摘要：

Electrical-field-induced dielectric anomalies in C-oriented 0.955Pb(Zn1/3Nb2/3)O-3-0.045PbTiO(3) single crystals were observed in both the dielectric constant and loss variations with temperature. Three distinct ordered phases are revealed, which are distinguished by their frequency dispersion behavior. We propose the existence of a medium-range ordered phase between the long-range and the short-range ordered phases, resulting from the competing features of the relaxor and ferroelectric constituents, Pb(Zn1/3Nb2/3)O-3 and PbTiO3. Some dispersion is evident in this medium-range ordered phase but global polarization is still present. The assumption is rationalized by the measured relationship between the remnant polarization and temperature. (C) 2003 American Institute of Physics.
