  "abstract": "Ordering processes in fcc-alloys with composition A_3B (like Cu_3Au, Cu_3Pd, CoPt_3 etc.) are investigated by Monte Carlo simulation within a class of lattice models based on nearest-neighbor (NN) and second-neighbor (NNN) interactions. Using an atom-vacancy exchange algorithm, we study the growth of ordered domains following a temperature quench below the ordering spinodal. For zero NNN-interactions we observe an anomalously slow growth of the domain size L(t) \\sim t^\\alpha, where \\alpha \\sim 1/4 within our accessible timescales. With increasing NNN-interactions domain growth becomes faster and \\alpha gradually approaches the value 1/2 as predicted by the conventional Lifshitz-Allen-Cahn theory.",
