Temperature dependences of the linear dimension L(T) and the optical path difference D(T) of the ferroelectric diglycine nitrate crystals, (NH₂CH₂COOH)₂ HNO₃, have been measured for three principal directions of optical indicatrix in the range of 130-295 K including the phase transition point Tc = 2...
