Abstract
The growth of the spin glass correlation length has been measured as a function of the waiting time on a single crystal of CuMn (6 at. %), reaching values nm, larger than any other glassy correlation length measured to date. We find an aging rate 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.
