Abstract: The absolute value of the local field in spin glasses determines the spin-flip probability. The average domain size for zero and nonzero absolute values of the local field in the ±J spin glass is calculated using the Monte Carlo method and related to dynamical heterogeneities. It turns out that the average domain size for nonzero absolute values of the local field, corresponding to slow spin dynamics at low temperature, increases and saturates with decreasing temperature, mainly due to the increase in the probability of finding nonzero local fields.
