Spin-Polarized Inverse Photoelectron Spectroscopy of Solid Surfaces: Ni(110)
John Unguris, A Seiler, Robert Celotta, Daniel T. Pierce, Philip Johnson, N. Smith
Inverse photoemission spectra have been measured on Ni(110) at 9.7-eV photon energy with a spin-polarized electron source. Consistent with band theory, a d-band-derived peak is observed just above the Fermi level that corresponds to transitions to minority-spin states only, and which increases in intensity and displays a slight (0.1-eV) energy dispersion as the angle of electron incidence is increased. The inelastic background displays an unexpected nonzero ( -5%) polarization.
