Resonant photoemission and magnetic x-ray circular dichroism in the M shell of ultrathin films of Fe
- Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)
Using magnetic ultra thin films (2--4 ml) of Fe on Cu(001) and bulk-like Fe, the Fe3p and Fe3s core states have been investigated with resonant photoemission and core-level photoemission, including, magnetic x-ray circular dichroism (MXCD) experiments. The resonant photoemission experiment has been done in fine steps over a wide photon energy range (h{nu} = 695 eV {minus} 715 eV), to probe the parentage of various spectral structures. The onset of secondary channels at the L{sub 3}(h{nu} = 707 eV) and L{sub 2}(h{nu} = 720 eV) edges will be analyzed in light of results from bulk Ni. The MXCD photoelectron spectroscopy of the Fe3p exhibits a 0.2 eV shift with circular polarization variation. The previously observed split peak structure in the Fe3s will be discussed with regard to the new resonant photoemission results. The resonant photoemission results will also be put into the context of our MXCD absorption results for monolayer and multilayers of Fe.
