Abstract

Antiferroelectric (Pb, La)(Zr, Sn, Ti)O₃ (PLZST) single crystal has been grown and characterized. From dielectric measurements, x-ray diffraction analysis, and in situ observation of domain structures, we found two first-order phase transitions during heating from room temperature to 250°C: orthorhombic (O) → rhombohedral (R) → cubic. Coexistence of O and R phases, with the R phase region strongly restricted inside the O phase matrix, has been observed within a broad temperature range above 123°C. In addition, much denser domain walls appeared in the PLZST crystal when the O-R transition takes place.
