From the nuclear spin rotation of implanted ⁵⁴Fe nuclei, we have determined the local susceptibility, the spir dynamics, and the width of the distribution of local magnetic fields of Au_1-xFeₓ(x=10^-4-5×10² at.%) spin glasses far above the freezing temperature. The width of this distribution was found to be proportional to the freezing temperature. The mean field freezing temperature, as obtained from the field distribution, was found to be a factor of 5 higher than the experimentally observed freezing temperature.
