Photoemission of spin-polarized d states in gadolinium

Recently, spin-polarized photoemission from gadolinium films was interpreted in terms of a 4f → 5d resonant scattering mechanism. In view of our photoemission data, we believe that this mechanism is very unlikely. Instead, the spin-polarization data can be explained in a straightforward manner taking into account the Gd band structure and simple photoemission escape cone rules. © 1982.
