Domain-related phase transitionlike behavior in lead zinc niobate relaxor ferroelectric single crystals

摘要

The relaxor ferroelectric lead zinc niobate (Pb(Zn_1/2Nb_2/3)O_3) has been intensively investigated, because of its large dielec- tric and piezoelectric properties for applications in actua- tors and transducers. In this study, the in-situ behavior of the domains in Pb(Zn_1/3Nb_2/3)O_3 single crystals has been observed using optical microscopy in combination with a charge-coupled device (CCD) camera.
