摘要The geometries, electronic, and magnetic properties of the 3d, 4d, 5d impurities encapsulated in an icosahedral Ag-12 cage have been systematically investigated by using relativistic all-electron density functional theory with generalized gradient approximation. The general features of the properties of 3d, 4d, 5d transition-metal atoms doped Ag-12 Clusters are probed and compared. It is found that the most stable structure for all M@Ag-12 clusters (M = 3d, 4d and 5d transition-metal atoms) is the icosahedral structure with I-h symmetries, in which the transition-meta I atom is located in the center of the Ag-12 cage. All doped clusters show larger relative binding energies compared with pure icosahedral Ag-13 cluster, indicating that doping by 3d, 4d, 5d transition-metal atoms could stabilize the Ag-12 icosahedron and form a new binary alloy cluster. The calculation of the magnetic properties demonstrates that the magnetic moments of M@Ag-12 clusters vary from 0 to 4 mu(B) by doping different transition-metal atom into Ag-12 icosahedron, suggesting that the transition-metal-doped Ag-12 clusters could have potential utility in new nanomaterials as building blocks with tunable magnetic properties.
