Abstract
Activated dynamics are established in , which is a model compound for the two-dimensional Ising spin-glass with random nearest-neighbor bonds. Cole-Cole analysis of the ac complex susceptibility reveals an extremely wide distribution of relaxation times, and a divergence, extracted to cover sixteen decades, of the median relaxation time towards K according to , with . Activated dynamic scaling of the out-of-phase susceptibility is found to hold over a wide range of temperatures and frequencies. Estimates for the critical exponents , , and are given.
