Re-entrant of normal dielectric permittivity-voltage hysteresis due to molecular relaxation in SmC∗ phase

The re-entrant of the normal hysteresis behavior has been observed at higher frequency in dielectric constant-voltage characteristics due to the induced polarization for dipolar rotation in SmC∗ phase. Absorption peak in the dielectric spectra due to the molecular rotation can be distinguished from that of appearing due to the cell relaxation.
