JOURNAL OF ELECTRON SPECTROSCOPY AND RELATED PHENOMENA
Spin resolved resonant photoemission from paramagnetic Gd(0001)/W(110) was
performed in the 4d --> 4f excitation region using circularly polarized rad
iation from the new helical undulator UE 56/1 at BESSY II. The general spec
tral behaviour of the electron spin polarization, including changes of its
sign, revealed in the Gd F-7 photoemission peak coincides with the MCD (mag
netic circular dichroism) asymmetry from ferromagnetic Gd. This similarity
is substantially due to the spin-orbit interaction, which identically deter
mines the (primary) excitation in both processes. (C) 2001 Elsevier Science
