The effect of ion ordering on the dielectric and electrooptical properties of lead scandium niobate and tantalate crystals
Abstract
High-temperature anomalies were observed in the epsilon and tg delta dependences for perovskite-structure lead scandium niobate and tantalate crystals. It is shown that the lattice ordering of cations has a significant influence on the character of these anomalies and on the magnitude of the photorefractive effect.
