Abstract
Secondary electrons from Gd(0001) films grown on W(110) show spin pola rization values of 28-34% in the energy range 1.5-7 eV at 150 K. No in dication of a polarization enhancement is found. Below 1.5 eV the pola rization drops to 20%, which is attributed to the presence of the 4f8 states just above the vacuum level.
