  Cu$_{0.5}$Co$_{0.5}$Cl$_{2}$-FeCl$_{3}$ graphite bi-intercalation compound   Non-equilibrium aging dynamics in 3D Ising spin glass
Cu$_{0.5}$Co$_{0.5}$Cl$_{2}$-FeCl$_{3}$ GBIC has been studied by zero-field
cooled (ZFC) magnetization and low frequency AC magnetic susceptibility ($f =
0.05$ Hz), where $T_{g} = 3.92 \pm 0.11$ K. The time dependence of the
relaxation rate $S(t) = (1/H)$d$M_{ZFC}/$d$\ln t$ for the ZFC magnetization
after the ZFC aging protocol, shows a peak at a characteristic time $t_{cr}$
near a wait time $t_{w}$ (aging behavior), corresponding to a crossover from
quasi equilibrium dynamics to non-equilibrium. The time $t_{cr}$ strongly
depends on $t_{w}$, temperature ($T$), magnetic field ($H$), and the
temperature shift ($\Delta T$). The rejuvenation effect is observed in both
$\chi^{\prime}$ and $\chi^{\prime\prime}$ under the $T$-shift and $H$-shift
procedures. The memory of the specific spin configurations imprinted during the
ZFC aging protocol can be recalled when the system is re-heated at a constant
heating rate. The aging, rejuvenation, and memory effects observed in the
present system are discussed in terms of the scaling concepts derived from
numerical studies on 3D Edwards-Anderson spin glass model.
