Abstract
The temperature dependence of the dielectric susceptibility is studied here for the smectic A-isotropic liquid transition of the ferroelectric A7. From the analysis of the experimental data for the dielectric constant, the critical behavior of the dielectric susceptibility is described close to the smectic A-isotropic liquid transition in this liquid crystal.
