The report shows the temperature behavior of the real part of dielectricpermittivity in the static (dielectric constant) and lo-frequency (LF) domainsin bulk samples of 11CB and BaTiO3-based nanocolloids. The study covers theIsotropic Liquid (I), Nematic (N), Smectoc A (SmA) and Solid CRystal (Cr)phases. For each phase, the dominance of pretransitional fluctuations,significantly moderated by nanoparticles is shown. The authors considerseparate focus on dielectric constant(Eps(T)) evolution in the static domainyielding mainly response from permanent dipole moments and their arrangementand in the low-frequency (LF) domain DeltaEps'(f)=Eps'(f)-Eps(where Eps'(f) isfor the real part of dielectric permittivity in the LF domain).which isassociated solely with ionic-related polarization mechanism. All these lead tonew experimental evidence concerning I-N, N-SmA and SmA-Cr transitions.focusingon the strength and extent of pretransitional effects, critical exponents andphase transition discontinuities. The strong evidence for pretransitionaleffects near SmA-N transition is notable, particularly regardingDeltaEps'(f,T). Studies are supplemented by DC electric conductivity - theparameter also related to LF domain. Finally, the validity of the relationEps'(f,T) = Af^(-3/2)+Eps (where f stands for the frequency and A is a constantparameter) often used for discussing dielectric spectra in LC compounds and itsnanocollids in the LF domain, is examined.
