Abstract

We report the fixing of a photorefractive grating in KTa1-xNbxO3 . The procedure involves the writing of a photorefractive grating in the cubic phase and the cooling of the sample under an applied field into the rhombohedral phase. We discuss possible mechanisms responsible for the effect.
