ABSTRACT = {This paper studies the size-dependent freezing of Co, Co-Ni, and CoCu clusters by using molecular dynamics with a general embedded atom method.
There is size effect occurs in these three types of clusters. The clusters with large
sizes always freeze to form their bulk-like structures. However, the frozen structures for small sizes are generally related to their compositions. The icosahedral
clusters are formed for Co clusters (for ≤3.2 nm diameter) and also for Co-Ni clusters but at a larger size range (for ≤4.08 nm). Upon Co-Cu clusters, decohedral
structure is obtained for small size (for 2.47 nm). The released energy induced
the structural transformation plays a key role in the frozen structures. These results indicate that the preformed clusters with special structures can be tuned by
controlling their compositions and sizes.},
