Title: Splitting of the phase transition in ferroelectric solid solutions Sn/sub 2/P/sub 2/(Se/sub x/S/sub 1-x/)/sub 6/

Abstract

The influence of the temperature and hydrostatic pressure on the forbidden band width and dielectric permittivity of the ferroelectric solid solutions Sn/sub 2/P/sub 2/(Se/sub x/-S/sub 1-x/)/sub 6/ (x = 0.04, 0.20, 0.30) is investigated. A change in the species and splitting of ferroelectric phase transition lines are detected for p = 0.140 and 0.026 GPa, respectively, for the solid solutions Sn/sub 2/P/sub 2/(Se/sub 0.04/S/sub 0.96/)/sub 6/ and Sn/sub 2/P/sub 2/(Se/sub 0.20/- S/sub 0.80/)/sub 6/, which is due to the existence of a Lifshits critical point separating the transitions into codimensional and noncodimensional phases on the p, T diagram. Shift coefficients with the pressure of the phase transition temperature are found for the solid solutions investigated.
