文摘

Experimental investigation of the thermal linear expansion L(T) and temperature dependences of the interference optical path difference D(T) have been conducted for ferroelectric diglycine nitrate (DGN) crystals, (NH₂CH₂COOH)₂HNO₃, for three principal directions of optical indicatrix in the range of 130–295 K including the phase transition point T_c
