Among the known properties of spin-glasses, one of the most typical is the non-stationary dynamic response of these systems when they are quenched into their low temperature phase. This aging phenomenon has been found in practically all the investigated materials whether metallic or insulating. The non-stationary dynamics is easily evidenced in the relaxation experiments, for instance the time decay of the thermoremanent magnetization (TRM). The decay is found to depend on the time tw the system has spent at the working temperature after a quench from above the freezing temperature Tg, before the field is switched off. When the observation time tobs (tobs = 0 at the field cutoff) becomes larger than tw, the response function is dominated by the non-stationary contribution.
