摘要：
We present concrete evidence for the formation of ferroelectric domain gratings induced by photorefractive space-charge electric fields in top-seeded solution-grown barium titanate crystals. These domain gratings are not destroyed by light and, by applying a field, can be reconverted into photorefractive gratings that diffract much more light than the photorefractive gratings that create them, as much as 67% of an incident beam.
