英文摘要The geometries, stabilities, and magnetic properties of Cr@Au-n (n = 1-8) clusters have been studied by means of a density functional method PW91P86 and a LanL2DZ basis set. It is found that the Cr atom in the lowest energy Cr@Au-n isomers tend to occupy the most highly coordinated position and the ground state configuration of the Cr@Au-n clusters favor a planar structure, except for n = 1. Maximum peaks are observed for the ground state Cr@Au-n clusters at n = 1, 5 on the size dependence of second-order energy differences, fragmentation energies, and HOMO-LUMO energy gaps, implying that the AuCr and Au5Cr clusters are magic clusters with relatively higher chemical stability. The magnetism calculations for the most stable Cr@Au-n clusters, which have a charge transfer from chromium atom to gold atoms, demonstrate that the total magnetic moment of the clusters is mainly localized on the Cr atom.
