Abstract
Abstract Relaxor ferroelectrics exhibit unique characteristics such as a broad phase transition and frequency dispersion which may originate from the configuration of ferroelectric microdomains. In this study, the dynamic behavior of the macrodomains in Pb(Zn1/3Nb2/3)O3 single crystals was observed using an optical microscope in combination with a CCD camera system. Many domain characteristics such as changes in birefringence, transition between microdomains and macrodomains, and “freeze-in” temperature of the macrodomains were optically observed. These observations were then compared to measured dielectric properties in an attempt to clarify the relationship between the dielectric properties and the behavior of macrodomains.
