摘要

We report on the temperature and mass dependence of the nearly constant loss (NCL) in several ionically conducting materials, both crystalline (Li-0.18 La-0.61 TiO3 and (Y2O3)(0.16) (ZrO2)(0.84)) and glassy (M2O . 3B(2)O(3), M = Li, Na, K and Rb). The magnitude A of the NCL is found to be larger for those materials showing higher dc conductivity values at room temperature, and shows weak temperature dependence of the form A proportional to exp(bT) in all cases. We have also found that A systematically decreases upon increasing the mass of the mobile alkali ion in the borate glasses. All these results point to the relaxation of ions in a very slowly decaying cage as the origin of the NCL. (C) 2002 Elsevier Science B.V. All rights reserved. [References: 34]
