Abstract

Optical gyration G, birefringence Δn and their electric-field E dependences of transparent ceramics of Pb_0.92La_0.08(Zr_0.65Ti_0.35)_0.98O₃ were studied by using high accuracy universal polarimeter (HAUP) in a temperature range between 10°C and 130°C. The high-temperature phase manifested neither spontaneous nor induced G, while the low-temperature phase did characteristic hysteresis loops of G and Δn with respect to E. Group-theoretical consideration of gyro-optical properties of both phases led us to the conclusion that the high- and low-temperature phases are cubic T_h and trigonal C₃, the same as found in Pb_0.92La_0.08(Zr_0.70Ti_0.30)_0.98O₃ ceramics. The free-energy function of both phases was determined by using these electro-optic effects. It is found that both ceramics undergo the same phase transition and manifest similar dielectric and optical properties.
