摘要: The discovery of dynamic memory effects in the magnetization decays spin glasses 1983 marked a turning point study highly disordered glass state. Detailed studies have led tomuch progress understanding qualitative features phase space. Even so, exact nature decay functions has remained elusive, causing confusion. In this Letter, we report strong evidence that thermoremanent scale with waiting time t w . By employing series cooling protocols, demonstrate rate at which sample is cooled to measuring temperature plays major role determination scaling. As effective e f c decreases, t/t scaling improves and for < 20 s find almost perfect scaling, i.e., full aging.
