Surface state contribution to the magnetic moment of Ni(111)
Spin-resolved inverse photoemission measurements on Ni(111) reveal a crystal-induced surface state close to the Fermi level that is partly occupied around the bar Gamma point of the surface Brillouin zone. This finding, together with an observed splitting of about 100 meV between spin-up and spin-down states, identifies this state as a truly magnetic state contributing to the surface magnetic moment of Ni(111). A photon polarisation analysis shows that the state has Lambda(1) symmetry at bar Gamma, therefore being derived from the p-like L(2') bulk state.
