The relaxation of the soft mode is observed both in the Sm A and Sm C^* phases by eliminating the contribution of the Goldstone mode under a dc bias field. Three relaxations are observed in the Sm C^* phase at the frequency range below 10 MHz. The temperature dependence of the dielectric constant originating in the soft mode shows a sharp peak at the phase transition temperature between the Sm A and Sm C^* phases, and shows Curie type behavior. An anomalous dip just below the peak of the dielectric constant is also observed at very high frequencies.
