A study of cole diagrams of some alkali halide relaxation maxima appearing at temperatures above 100°C

Relaxation maxima occurring at a frequency of 1 kHz above 100°C in pure LiF, KCl, NaCl and CaCl₂-doped NaCl were investigated and an interesting fact, the dependence of the relaxational loss angle as well as the resp. dielectric constant on the sample thickness, was found and discussed.
