Abstract :
The comparison of different experimental methods of dielectric relaxation measurements applied to diverse ionic solids clearly demonstrates that ac conductivity dispersion observed in these solids is of dielectric nature. Then, by analysing the dielectric signal in terms of distribution of relaxation times, we show that important information on material can be obtained. They are for instance the interaction energy between the ionic charges and their surrounding network or the different types of sites where ions are embedded.
