Article Description

First-principles calculations, based on the local-spin-density approximation, are performed for cobalt atoms deposited on noble-metal surfaces. The local density of states at the cobalt site shows a narrow peak at the Fermi energy, which is of minority spin and d character. The d orbital of (Formula presented) symmetry, which must be mostly responsible for tunneling conductance from this surface site, makes a substantial contribution at (Formula presented) Due to hybridization the same peak also appears, but reduced, at neighbor atoms. This result can be used for the interpretation of recent cryogenic scanning tunneling microscopy experiments. © 1999 The American Physical Society.
