The spin densities at the Fermi energy for the clean and oxygen adsorbed Fe(110) surfaces calculated using the full potential linearized augmented plane-wave method are found to differ substantially (in sign) from the energy-integrated total spin density previously given in the literature. The energy-sliced spin density becomes negative in the Fe(110) surface-vacuum region despite the enhancement of the surface magnetic moment and is reversed in sign, to positive, by the addition of a p(1×1) oxygen overlayer. Both results have been observed in a recent experiment using spin-polarized metastable atom deexcitation spectroscopy.
