Abstract

The low frequency dielectric relaxation has been studied for the SmC^* phase of the room-temperature ferroelectric liquid crystal mixture. The dielectric spectra have been measured on the planar oriented sample in the frequency range from 100 Hz to 100 kHz with the electrical measuring field being parallel to the layer planes. From experimental results presented in this work one can see that: 1) when the structure of sample for the SmC^* phase is helicoidal the dielectric relaxation of the studied material is shown to have the strong electric measuring field dependence, and 2) when the SmC^* structure is completely unwound a low frequency weak relaxation is detected; the relaxation frequency of this mode increases with increasing bias field.
