Frequency dielectric dispersion in the ferroelectric and superionic phases of CsH2PO4

Abstract
The complex admittance was measured for CsH2PO4 in the frequency range from 30 Hz to 60 MHz and in the temperature range 90-550 K. The domain wall relaxation time was found to decrease anomalously when approaching to Tc. From the investigations of the conductivity of CDP the structural phase transition at Tsi.=503K was shown to be superionic.
