We have studied the relaxation rate of the magnetization of a single crystal of Bi2Sr2CaCu208 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].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
