Abstract

The effects of B-site ordering and vacancies were studied in the relaxor ferroelectric Pb(Sc_1/2Nb_1/2)O₃ (PSN) family by using Raman scattering spectroscopy. Differences with Raman spectra and the depolarization ratios were clearly observed among B-site disordered PSN (PSN-D), B-site ordered with lead/oxygen vacancies PSN (PSN-OV), and 0.7Pb(Sc_1/2Nb_1/2)O₃-0.3PbTiO₃ (PSN-30PT) single crystals. The temperature dependence of the depolarization ratio of PSN-30PT was also studied to clarify the ferroelectric phase transitions and the polarization fluctuations in the polar nanoregions.
