Single crystals of Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 (PIN-PMN-PT) poled along [001] were investigated by dielectric, x-ray, and polarized light (PLM) and piezo-force microscopy (PFM) methods. PLM revealed 100 macro-domain plates that formed after poling, whose size increased on heating between room temperature and a rhombohedral → tetragonal phase transition, above which point a break-up of the macro-domain plates was observed. Corresponding PFM studies demonstrated that poling reduced the size of stripe-like domains that were internal to the macro-domain plates, whose size also increased on heating to TR-T. The temperature dependence of both the size of the macro-domain plates and internal sub-domains followed the Arrhenius relation with the activation energy of 0.4-0.5eV. The coercive field displays an abnormal increase on heating below TR-T, different than that for PMN-PT. The anomalously increased coercive field can be ascribed to the Arrhenius-type domain growth, indicating a simple thermally activated process and an important role of hierarchial domains in the improved performance of PIN-PMN-PT.
