Abstract
The time dependence of the magnetization of the dilute spin-glass Ag:Mn (2.6 and 4.1 at.%) prepared in the field-cooled state has been measured after the field has been cut off at a constant waiting time. The time dependence is found to be of the stretched exponential form, with a rate constant which varies exponentially with inverse temperature. This result appears consistent with an exponential distribution of independent, random free-energy levels in the spin-glass phase.Keywords
