Abstract

Experimental studies of thermal expansion and spontaneous polarization of ferroelectric deuterated triglycine sulfate crystals with the deuteration degree 0.7 are performed. The main dilatometric parameters and the electrostriction coefficients are found. Fluctuations of the order parameter of the phase transition are interpreted in the framework of the known modified Landau theory.
