Özet

We calculate here. the dielectric constant E as a function of temperature for the AC* phase transition of a ferroelectric liquid crystal using a mean field model. Using the values of the polarization P and the tilt angle theta, calculated from the mean field model with the P-2 theta(2) coupling for 4-(3-methyl-2-chlorobutanoyloxy)-4'-heptyloxybiphenyl, the dielectric constant E is calculated in the smectic C* phase of this ferroelectric liquid crystal at various temperatures at constant electric fields.
