Abstract
The time decay of the thermoremanent magnetization, σTRM (t), of Eu0.54Sr0.46S was measured in the spin-glass phase. Two time responses were found, for short times : σTRM (t) decays as a power law ; for long times, σTRM (t) decays as a stretched exponential. The time separating the two regimes increases with waiting time.
