摘要：

Broadband dielectric spectroscopy (10-1109 Hz, 100450 K) was employed to study a pure ferroelectric liquid crystal containing only a single dipole moment in the chiral terminal group. In addition to the Goldstone and soft mode the high-frequency order-parameter fluctuations in the smectic-A phase and chiral-smectic-C phase could be found as predicted theoretically by Blinc and aeka [Phys. Rev. A 18, 740 (1978)]. © 1990 The American Physical Society.
