Abstract
We present a scaling analysis of the nonlinear susceptibility data above the freezing temperature in the spin glass system Fe0.25Zn0.75F2. The critical exponents obtained are in excellent agreement with those found in metallic systems and are also compatible with theoretical predictions for short range Ising spin glasses.
