✦ Synopsis

The depcndcncc of pit& on electric field strength E and of the critical electric iield EC on temperature in the smectic C* phase or the fcrroelcctric liquid crystal 2-meth)lbutJ lp-[p-rl-dec~lo~~bcnz~lidencammol_cinnamate has been determined Near the SmC* -SmA transition anomalous bchaviour of the pitch was observed. The exponenr~ relating the critical electric field and temperature. EC a (7, -I-)-' , xvas found to be 0 54 + 0.05. The reentrant SmC* phase was observed in the electric tield.
