| Abstract(in English) | In this study, the time dependence of the magnetization process in amorphous TbFeCo thin films and(TbFeCo / Pt)multilayers is studied. By assuming a Gaussien distribution of relaxation times for magnetic aftereffect, we were able to describe the non-Arrhenius behavior of the magnetization decay shown in almost all of our samples. From a fitting of experimental data one can determine the mean value of relaxation time τ_o and also its width Δτ_o. The multilayers of TbFeCo / Pt show a high stability compared to monolayers of TbFeCo with also a small activation volume. |
