摘要：

The time decay of the thermoremanent magnetization has been measured in Ag:Mn (2. 6%) below T//g for a wide range of waiting and observation times. A scaling analysis of the aging process has been applied and the curves obtained for different waiting times could be superimposed on a unique master curve. At each temperature, the master curve defines the response function of the system for a given age. At very small fields, this response function is well represented by the product of a power law and a stretched exponential.
