Abstract
Ferroelectric domain structure and evolution, as well as phase transition, of [001]-oriented 34Pb(In1/2Nb1/2)O3-0. 25Pb(Mg1/3Nb2/3)O3-0.41PbTiO3single crystal has been studied through temperature and frequency-dependent relative permittivity characterization. Under dc bias, the transition temperature from rhombohedral-to-tetragonal phases becomes lower and the transition temperature from macrodomain to microdomain structures increases. Phase transition from rhombohedral to tetragonal is confirmed by temperature-dependent x-ray diffraction. These results are also well supported by direct domain observation by means of piezoresponse force microscopy under dc bias at different temperatures, as well as polarization-electric field hysteresis loop measurement.
