Relaxation time distribution of deuterated dipole glass

Abstract

We have shown that none of the well-known relaxation functions such as the Cole-Cole, Cole-Davidson and KWW functions are satisfactory to describe the observed dielectric relaxation behavior of the deuterated rubidium-ammonium dihydrogen phosphate dipole glass (DRADP-x). The correlated domain model of Chamberlin was in qualitative agreements with the experimental observations of the dipole glass for (i) a long tail at lower frequency side, (ii) increase in the asymmetry of the dielectric loss spectrum with decreasing temperature.
