Abstract
Spin-resolved photoelectron spectra of a monolayer of xenon atoms phys isorbed on magnetized Fe(110) and Co(0001) surfaces have been taken us ing unpolarized VUV light. The spin-resolved spectra reveal the Xe 5p signal being split by up to 0.24 eV. This spin splitting can be explai ned by magnetic adsorbate-substrate interactions which have previously been observed only for strongly chemisorbed species. The results indi cate physisorbed rare-gas atoms acting as a kind of ''atomic probe'' f or local surface magnetism.
