Research output: Contribution to journalArticlepeer-review


We present the observation of glasslike dynamic correlations of mobile mercury ions in the ionic conductor Cu 2HgI 4, detected in both NMR and nonlinear conductivity experiments. The results show that dynamic cooperativity appears in systems seemingly unrelated to glassy and soft arrested materials. A simple kinetic two-component model is proposed, which seems to provide a good description of the cooperative ionic dynamics.
