Abstract
Complex dielectric constants of Rochelle salt(RS)-ammonium Rochelle sa lt(ARS) mixed crystal system have been investigated with a conventiona l LCR-meter at temperatures from 20K to 295K at 10kHz. The obtained da ta have been plotted on the epsilon'-epsilon '' plane, and they show a fairly continuous locus. They show considerable difference among the region I(0 < x < 0.025), the region II(0.025 < x < 0.18) and the regio n III(0.18 < x < 0.92). The temperature where the epsilon '' is maximu m is in the region of the ferroelectric phase in the region I and the region III. In the region II, the maximum point of the epsilon '' is t he higher temperature side than the temperature where the epsilon' is maximum.
