Switching of optical rotatory power in ferroelectric 5pbo 3Ge02 single crystal

Abstract

An enantiomorphic transition was observed for the first time by observing Airy's spirals of the oppositely polarized ferroelectric 5PbO 3GeO2 single crystals, which were grown by the Czochralski method. Switching time follows an exponential law at moderate field strengths and a power law at higher field strengths.
