Spin-resolved inverse photoemission measurements on Ni(111) reveal a c
rystal-induced surface state close to the Fermi level that is partly o
ccupied around the GAMMABAR point of the surface Brillouin zone. This
finding together with an observed splitting of about 100 meV between s
pin-up and spin-down states identifies this state as a truly magnetic
state contributing to the surface magnetic moment of Ni(111). A photon
polarization analysis shows that the state has LAMBDA1 symmetry at GA
MMABAR, therefore being derived from the p-like L2' bulk state.
