The growth of the spin glass correlation length has been measured as a function of the waiting time $$t_ w$$ on a single crystal of CuMn (6 at. %), reaching values $ξ ~ 150$ nm, larger than any other glassy correlation length measured to date. We find an aging rate $d ln $$t_w/d ln $$ξ$$ larger than found in previous measurements, which evinces a dynamic slowing down as $$ξ$$ grows. Our measured aging rate is compared with simulation results by the Janus Collaboration. After critical effects are taken into account, we find excellent agreement with the Janus data.
