Memory and Rejuvenation in Glassy Systems
arXiv:2305.17296 · doi:10.1103/PhysRevB.110.L060411
Abstract
The memory effect in a single crystal spin glass () has been measured using \freq ac susceptibility techniques over a temperature range of and a model of the memory effect has been developed. A double-waiting-time protocol is carried out where the spin glass is first allowed to age at a temperature below , followed by a second aging at a lower temperature, \Tw{2}, after it has fully rejuvenated. The model is based on calculating typical coincident growth of correlated regions at the two temperatures. It accounts for the absolute magnitude of the memory effect as a function of both waiting times and temperatures. The data can be explained by the memory loss being a function of the relative change in the correlated volume at the first waiting temperature because of the growth in the correlations at the second waiting temperature.
