Abstract: The structure and energetic of Palladium-Cobalt clusters(N = 11–20)have been studied extensively by a Monte Carlo method based on Sutton–Chen many-body potential. The basin-hopping algorithm was used to determine the global minima of bimetallic clusters. The structural changes with cluster size were observed. Most of the structures had built on icosahedral packing. Second energy difference analyzes were performed to investigate the relative stability of a cluster with respect to its size and composition is discussed.
