摘要：

The results of the studies of the influence of a constant electric field, directed along the spontaneous polarization axis, on the temperature behaviour of the dielectric constant of the proper uniaxial ferroelectric Sn(2)P(2)S(6), bears witness to the proximity of the second-order ferroelectric phase transition (PT) to the tricritical point. They also confirm the dependence of the Lifshitz point coordinates in the mixed S(2)P(2)(Se(x)S(1-x))(6) crystal phase diagram on the degree of non-equilibrium of the electron subsystem in these semiconductors.
