Abstract: The results of the study of dynamic processes of repolarization of crystals of pure and deuterated triglycine sulfate are presented. It is established that deuteration and an increase in the concentration of the alanine impurity in deuterated crystals lead to a decrease in the relative and effective dielectric constants, switchable polarization and an increase in the coercive field and the displacement field. Deuteration and substitution of a part of glycine molecules into alanine allows obtaining a stable unipolar state in crystals.

Keywords: processes of switching, domain structure, triglicinsulfate, deuteration, scanning electron microscopy.
