Spontaneous polarisation P, and tilt angle 0 of induced ferroelectric Sy phases in mixed systems were measured as a function of mole fraction xo. Both quantities depend non-linearly on the composition of the mixture, but the quantity PO= P,/sin 0 shows a linear dependence on xo. A new material const

✦ Synopsis
Ferroelectnnty has been observed m hquid crystallme muttures of chiral smectic C type with a helical structure induced by choral guest molecules (pitch p = 100 pm). Samples of thtckness d < p form monodomams with ftite zero+?eld electric polarlzatlon because the spontaneous polarization of the smecttc layers is not compensated by the helical twst. The temperature dependence of the spontaneous polanzation has been studied near the phase transition smectic C -smectic A,
