Abstract (english)

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.
