Exchange splitting of sp-like surface states on Ni(001)
Spin-resolved inverse photoemission is employed to investigate crystal-induced and image potential surface states on Ni(001). There is experimental evidence of a nonvanishing exchange splitting of the image potential state at the centre of the surface Brillouin zone. These data are consistently described within the framework of a multiple reflection model for surface states if the upper band-gap boundaries are assumed to be exchange split by 200 meV at this point. This splitting was confirmed experimentally by spin-resolved target current spectroscopy.
