Abstract

The mixed crystals Sn2P2(SexS1_x)6 are proper rerrolectrics who- se phase diagram contains a Llfshltz point that separates the transi- tions to the commensurate and Incommensurate (IC) phases. The P2 /c Pc phase transition of second order in Sni)P0S2 occurs at Ti"' 338 K. When some of the sulphur is replased by selenium, the line of conti nuous phase transitions splits smoothly into lines of transitions of the fint order - T1(x) and second order - To(x) that bound the IC phase'. _
