摘要：

We have made extensive high field thermoremanent magnetization decay measurements on Cu:Mn(6%), in magnetic fields between 5 and 6 kG, over a wide range of temperatures and for three different waiting times to examine spin glass dynamics in the previously unexplored Heisenberg regime. We have found aging effects for both transverse and longitudinal freezing, with crossover behavior between the two regimes. This provides the first dynamical experimental evidence consistent with the Heisenberg spin glass H-T phase diagram derived by Gabay and Toulouse.
