Temperature and electric field dependence of the dielectric property and domain evolution in [001]-oriented 0.34Pb(In[sub ½]Nb[sub ½])O₃–0.25Pb(Mg[sub ⅓]Nb[sub ⅔])O₃–0.41PbTiO₃ single crystal

Abstract

Ferroelectric domain structure and evolution, as well as phase transition, of [001]-oriented 34Pb(In[sub ½]Nb[sub ½])O₃–0.25Pb(Mg[sub ⅓]Nb[sub ⅔])O₃–0.41PbTiO₃ single 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.
