Dielectric Behavior of 95.5% Pb(Zn1/3Nb2/3)O-3-4.5% PbTiO3 Single Crystals under DC Bias from 12-550 K
This work reports a detailed study of the dielectric behavior of 95.5% Pb(Zn1/3Nb2/3)O-3 - 4.5% PbTiO3 (PZN-4.5PT) single crystals with and without dc bias. It is found that there are at least five sets of dielectric anomalies for PZN-4.5PT from 12K to 550K. There are two dielectric peaks, around 430K and 395K, which are referred to as cubic-tetragonal and tetragonal- rhombohedral phase transitions, respectively, above room temperature. Furthermore, a set of broad peaks around 350K (at 10kHz) that showed up under electric field of 10kV/cm might indicate the existence of a monoclinic distortion M-A phase.
