We have investigated the self-diffusion and thermodynamic quantities of AuCu supelatic using the statistical moment method in the statistical physics. The activation energy, diffusion coeffient, pre-exponential factor, lattice parameter, thermak expansion coefficent, etc…., are derived in closed analytic forms within the fourth order moment approximation. The present analytic formulas including the anharmonic effects of the lattice vibration give the predicted values of these quantities.
