Precision Monte Carlo simulations of labeled particle diffusion in mixed A-B alloys in two and three dimensions were reported. A variety of concentrations and ratios of the hopping rates JB/JA were analyzed. Results were compared with those predicted by available theories. The validity of these theories was observed to be strictly limited to the region where >1/z (z was the lattice coordination number).
