  The temperature- and electric field-dependent dielectric relaxation and polarisation of a new chiral swallow tailed antiferroelectric liquid crystal, i.e. 1-ethylpropyl (S)-2-lcub6-[4-(4`-decyloxyphenyl)benzoyloxy]-2-naphthylrcubpropionate (abbreviated as EP10PBNP), were investigated. The electric field-induced dielectric loss spectra of EP10PBNP revealed electroclinic and anomalous dielectric behaviour in the chiral smectic A (SmA*)-chiral antiferroelectric smectic C (SmCA*) pre-transitional regime. From an analysis of thermal hysteresis of the dielectric constant, electric field-induced polarisation and dielectric loss spectra, the appearance of a ferrielectric-like mesophase is observed followed by an unstable SmCA* phase in the SmA*-SmCA* pre-transitional regime.
