N2 - Electronic structures of AgnCo- (n = 6-8) were investigated by photoelectron spectroscopy and density-functional calculations. The local spin magnetic moments on Co were found to be 2.04, 1.48, and 0 μB for n = 6, 7, and 8, respectively. A strong sp-d interaction in n = 8 allows the Co 3d orbitals to form a closed electronic shell, whereas the Co 3d shells in n = 6 and 7 remain open with finite spins under a weak sp-d interaction. The present result demonstrates significant size dependence of an sp-d interaction in a metal cluster containing a magnetic impurity.
