Abstract
An anomalous dielectric relaxation process, called the partially unwound helical mode (p-UHM), is a collective dielectric process apart from the well known Goldstone and soft mode process; it is studied in the smectic () phase and at the transition temperature of the phase in the ferroelectric liquid crystal (FLC) material. To avoid the surface effect, a thick cell of 40 μm thickness was prepared with highly rubbed surfaces of the ITO substrates. It has been observed that the dielectric properties in and at the temperature are dominated by the p-UHM process which is dependent on an applied oscillating field in the phase. The probing ac and dc bias field dependences of all these collective dielectric processes have been reported in the and phases of FLC materials.
