摘要：
We have studied the relaxation rate of the magnetization of a single crystal of Bi2Sr2CaCu2O8 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) almost-equal-to 0.022 and S(0) almost-equal-to 0.15].
