Abstract

The fundamental optical absorption edge and dielectric permeability and its temperature and pressure dependence in the vicinity of phase transitions in (Sn0.95Zn0.05)2P2S6 ferroelectric crystals is measured . Based on these data, the p,T-phase diagram of   (Sn0.95Zn0.05)2P2S6 crystals is built.
