摘要：

Slow dynamics in the 3-dimensional isotropic Heisenberg spin glass (SG) model is investigated by Monte Carlo simulations. The spin autocorrelation function exhibits an exponential decay multiplied by an algebraic factor. The relaxation time of the exponential decay obeys the conventional dynamical scaling with T = 0 transition. However, the behaviour of the algebraic prefactor is rather peculiar, which may be regarded as one of the SG properties inherent in the model.
