DC field induced antiferroelectric phase transition in bulk, single crystal strontium titanate

Abstract

Dielectric hysteresis in bulk, single crystal SrTiO₃ (STO) with YBa₂Cu₃O₇. x(YBCO) electrodes is studied experimentally at 77K. In contrast with previously reported experiments [1], [2] the antiferroelectric phase transition is observed at higher temperature (i.e. 77K). The phase transition is observed where the crystal is cooled either with short circuited or with open circuited electrodes. The phase transition does not result in detectable changes in the microwave losses.
