| Abstract: | We report in this article the resolution of TSDC (Thermally Stimulated Depolarization Current) spectra and the relaxation parameters of Ce2(SO4)3· 9H2O(9D2O) single crystals, for two typical orientations parallel and perpendicular to C6, symmetry axes The TSDC peaks obtained show a nonDebye type of behavior Calculation of the dipolar relaxation parameters was achieved by fitting the experimental curves to a general order kinetic equation This method allows us to describe the nonDebye-type of behavior of the TSDC peaks on the basis of dipolar interactions during the relaxation process The three different kinds of electric dipoles leading to the three experimentally observed TSDC peaks are ascribed to three different configurations of hydrogen bonds. |
