Abstract

The ferroelectric spontaneous polarization P and the coercive voltage Vc and their frequency dependences have been measured in frequency range 10 Hz - 10 kHz. The exponents of power law P varies direct as f^-b and Vc varies direct as f^c have been found and confronted with theoretical predictions. The coefficient of rotational viscosity (gamma) has been computed.
