Abstract
Monte Carlo simulation is performed to study microscopically the zero-field spin-glass phase of the compound Fe0.25Zn0.75F2. We suggest that its under lying mechanism is the effective local random field distribution, which res ults from the fractal domain structure near the percolation threshold.
