The order–disorder transition temperature of CoPt nanoparticles depends on particle size and morphology. The predictions given by the bond‐energy model are consistent with recently published experiments in the literature, suggesting that the order–disorder transition of CoPt nanoparticles is a surface‐dominant phenomenon.
