Dynamic transport in ionic conductors
The experimental data for the dielectric response of certain ionically conducting ceramics obtained by Kuhn and coworkers were re-interpreted using the "universal" dielectric formalism and the results reveal the presence of two well defined processes with power law exponents of - 0.6 to - 0.7 for the high-temperature, low-frequency branch and - 0.3 and less for the low-temperature, high-frequency branch. The physical significance of these results is discussed in terms of transport in strongly anisotropic materials.
