      abstract     = {Results are presented of a first-principles calculation of
                      the spin-polarized field emission from ferromagnetic Ni(111)
                      and Ni(001) surfaces. The electronic structure of both
                      surfaces exposed to an external field is determined by
                      combining the surface-embedded Green function approach and
                      the full-potential linearized augmented plane-wave (FLAPW)
                      method within the local spin density approximation. We
                      discuss the contributions of different states to the
                      field-emission current. In particular, we show that
                      delocalized states make similar contributions to that
                      obtained at jellium surfaces while localized Ni d states
                      contribute mostly through surface states and resonances.
                      These contributions dominate in the minority spin and lead
                      to a negative spin polarization of the emitted current.},
