Investigation of the thermal linear expansion L(T) and temperature dependences of the interference optical path difference D(T) have been carried out for diglycine nitrate (DGN) crystals, (NH2CH2COOH)2xHNO3, in the range of 130-295K. Minimums of the temperature dependences of anisotropy degrees of dilatative (AL) and refractive (An-1) characteristics near Tc = 206K show effective disordering of the crystal at phase transition.

Keywords: ferroelectrics, dilatative and refractive properties
