摘要：

The dielectric spectra of lamellar compound CuInP2S6 is presented. Above 1 MHz the dielectric dispersion caused by diffuse soft mode appears. The ferroelectric dispersion in the vicinity of T-c begins at about 10 MHz and ranges up to the GHz region. Debye-type dispersion together with the critical slowing down shows the order-disorder type of phase transition.
