Abstract
We have studied the relaxation rate of the magnetization of a single crystal of before and after heavy-ion irradiation as a function of temperature for fields less than 1 T. We find a significant decrease in the thermally activated regime, and a moderate shift to lower values in the quantum regime after irradiation [respectively S(0)≊0.022 and S(0)≊0.15].
