We report time dependence measurements of the zero field cooled magnetization (MZFC) and the thermoremanent magnetization (TRM) for AuFe (2 and 4 at.%), AgMn (1 and 4 at.%), and Th1−xGdx (3⩽x⩽20 at.%) as a function of the magnetic field. The time effect behavior was similar in the three systems. The time dependence can be fitted with a log (t) law when the temperature T is not too close to the reversible temperature TR at which the magnetization becomes reversible. The rate of the TRM decay increased with H, presented a maximum with T, and extrapolated to zero when T→TR.
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.
