LINEAR MAGNETIC DICHROISM IN PHOTOEMISSION

Results for the linear magnetic dichroism of Fe 2p spin-resolved photo emission with high energy resolution are reported. The results are qua litatively similar to those for the 3p level, with the advantage that the fine structure split sublevels (j = 1/2 and j = 3/2) are well sepa rated, facilitating comparison with theoretical models. The finite dic hroism in the energy region between the two photoemission peaks is not caused by secondaries, but appears to be a nontrivial effect. The 3p dichroism depends on photon energy: it is maximum at 140 eV, and vanis hes around 300 eV photon energy.
