摘要: Small ${\mathrm{Ni}}_{m}({\mathrm{C}}_{60}{)}_{n}$ clusters with $n+ml~4$ are studied using the tight-binding molecular-dynamics method generalized to treat heteronuclear systems. Our results confirm recent experimental deduction of bonding behavior Ni towards ${\mathrm{C}}_{60}.$ The direction charge transfer is found depend on geometry cluster. Furthermore, present reveal a striking dissimilarity in between $\mathrm{Ni}\ensuremath{-}{\mathrm{C}}_{60}$ and Ni-graphite
