- 論文の詳細を見る
Complex dielectric constants of KH.P0. single crystals along the a- and the c-axes have been measured in the temperature range from 2.5 K to 30 K at fre-quencies between 10 Hz and 20 kHz. Dielectric dispersions with small loss peaksare observed in both directions. The dispersion along the c-axis (dispersion C)is found only in the multidomain crystal, whereas the dispersion along the a-axis (dispersion A) is insensitive to the domain structure. The relaxation frequencyof the dispersion C obeys the Arrhenius' relation with the extremely small activa-tion energy of 0.019 eV. A large deviation from the Arrhenius' relation is foundfor the dispersion A. The temperature dependence of the dispersion frequency andthe profile of the dispersion curves of the dispersion A are well explained by adamped oscillator model with a Gaussian distribution of the resonant frequencies.
