Recent experimental studies have shown that ferroelectric nanoparticles play an important role on smectic liquid crystals. These include the weakly discontinuous nature of the isotropic-smectic-A transition, the decrease of the temperature metric discontinuity, the decrease of the dielectric constant and a slight increase of the transition temperature. We described all these experimental observations within phenomenological theory. The impact of ferroelectric nanoparticles on the isotropic-smectic-A transition temperature, Kerr constant and non-linear dielectric effect is discussed. The theoretical predictions were found to be in good qualitative agreement with the experimental results.
