Resumen: The growth of the spin glass correlation length has been measured as a function of the waiting time tw on a single crystal of CuMn (6 at. %), reaching values ¿~150 nm, larger than any other glassy correlation length measured to date. We find an aging rate dlntw/dln¿ larger than found in previous measurements, which evinces a dynamic slowing down as ¿ 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.
