Anomaly of ε of CuInP2(Se0.9S0.1)6 of ferroelectric shifts to the lower temperature ronge and decrease under t influence of hydrostatic pressure. However, the value of thermal hysteresis and between difference Curie and Curie-Weiss temperature increase. Phase p, T-diagram is nonlinear with a negative coefficient , the absolute value of which increases with increase of pressure.
