摘要：
The investigation deals with birefringence and compressibility in Sn2P2S6 ferroelectrics crystals across the p, T-diagram. It enables the behaviour of the critical exponents to be determined and the behaviour of the coefficients in the thermodynamic potential expansion for these crystals in the vicinity of the Lifshitz point to be estimated.
