Abstract
A new Gly . H3PO3 crystal. was grown and its physical properties were investigated. DSC measurements revealed a phase transition at about 22 4 K. Dielectric investigations showed a large anomaly of dielectric pe rmittivity at 224.7 K along the b-axis. The appearance of spontaneous polarization (along the b-axis) observed by means of a Sawyer-Tower ci rcuit gives evidence for a para-ferroelectric phase transition in this material.
