Abstract

So far, most of the experimental results for the core-level spin-resolved photoemission from non-magnetic materials have been interpreted by a simple free-atom model. However, the multiple scattering exerts some influence on the spin polarization. We thus have theoretically investigated the effect of multiple scattering on the spin polarization in W4ƒ photoemission spectra from W(110) surface. The present multiple scattering calculation improves the agreement with the experimental results in comparison with the calculation using the free-atom model. To understand the effect of multiple scattering on spin polarization, we calculated the spin polarization from emitter atoms in the individual surface layers. We found that the forward scattering plays an important role. We also studied the effect of thermal factor on spin polarization, and found that it was quite small.
