Temperature dependence of the quadratic electrooptic effect and estimation of antipolarization of ADP

Abstract

Abstract Measurements of the temperature dependence of the quadratic electrooptic coefficient | g 1111 ‐ g 2211 | of ADP were made. The coefficient is found to decrease with an increase in temperature. The results show that the intrinsic quadratic electrooptic coefficient | M 1111 ‐ M 2211 | defined in terms of polarization also dependes on temperature. Employing the temperature dependence of | M 1111 ‐ M 2211 | estimation of antipolarization in lowtemperature antiferroelectric phase of ADP is made. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
