N2 - The effects of sulfur, as a prototypical catalytic poisoner on the structural, electronic, and magnetic properties of Ni(001) are investigated with the highly precise full-potential linearzed augmented-plane-wave method. The Si-Ni interlayer distance is determined to be 1.36. The poisoning is found to be caused by local Ni-S covalent-bond formation and the lone-pair density polarization on the S site. A nearly magnetically dead Ni surface layer (0.12B) is obtained. The indirect long-range (screening) interaction is manifested in a layer-dependent oscillatory on-site charge transfer between eg and t2g symmetry states for Ni inner layers.
