Abstract
The complex dielectric constant of TGS powders 74∼105 µm in particle size has been measured between 77 K and 340 K in the frequency range from 10 Hz to 105 Hz. Four types of dielectric relaxations are found in the ferroelectric phase. The relaxation frequencies obey the formula, f r=f oexp (-U/k T). The values of f o and U are determined to be 1×108 Hz and 0.33 eV, 4×1012 Hz and 0.35 eV, 9×1013 Hz and 0.33 eV, and 2×108 Hz and 0.06 eV, respectively, which are quite different from those of multidomain single crystals.Keywords
