“…This monochromator is especially designed to operate with linearly polarized ͑LP͒ as well as with right circularly polarized ͑RCP͒ and left circularly polarized ͑LCP͒ soft-x-ray radiation in the photon-energy range from 100 eV up to 1000 eV; for details on the optical configuration of the monochromator and the beamline, see Petersen and co-workers. 42,43 The schematic setup of the experiment at the PM3 beamline is shown in Fig. 1 in the case of using circularly polarized radiation.…”

The phenomena of magnetic circular and linear dichroism in the angular distribution ͑MCDAD and MLDAD͒ of photoelectrons manifest themselves in different photoelectron intensities in the related parts of their spectra when the sample is remanently magnetized in opposite directions. In combination with the experimental results carried out at the storage ring BESSY in Berlin, new fully relativistic photoemission calculations have been performed under the consideration of fully circularly and linearly polarized radiation in the soft-x-ray region. Here, we present the energetic dependence and the relationship between MCDAD and MLDAD in the energy range from hϭ90 to 175 eV. The physical origin of both phenomena is analyzed in detail with respect to the hybridization of the Fe 3p multiplet and the dynamics in this process is discussed.

“…12 The photons were incident at an angle of 15 o with respect to the film plane, and the photoelectrons were collected around surface normal by a hemispherical electronenergy analyzer. 100-Å-thick Gd͑0001͒ and Tb͑0001͒ films were grown epitaxially on W͑110͒ by vapor-phase deposition of high-purity Gd and Tb metal evaporated from electron-beam heated Mo crucibles, with the substrate at 270 K. The base pressure in the experimental chamber was typically 3ϫ10 Ϫ11 mbar, rising to 2ϫ10 Ϫ10 mbar during Gd and Tb evaporation.…”

Magnetic circular dichroism in 5pphotoemission from Gd and Tb metal

The isotropic and magnetic-circular-dichroism ͑MCD͒ 5p core-level photoemission ͑PE͒ spectra of Gd͑0001͒ and Tb͑0001͒ are presented. Large MCD effects were observed at the low-binding-energy side, gradually reducing in amplitude at higher binding energies. Both the isotropic and the MCD-PE spectra can be well reproduced by a many-particle intermediate-coupling approach taking spin-orbit, Coulomb, and exchange interactions properly into account. We also present a simple model to understand the global line shape of the MCD spectra. The MCD permits an accurate determination of the values of the Coulomb and exchange interactions in the final state.

Abstract.It is shown experimentally that in the soft X-ray region a large circular dichroism in the photoelectron angular distribution (CDAD) exists for both valence orbitals and core levels of CO molecules adsorbed on Pd(111). From theoretical consideration it follows that in the case of a spherically symmetric ground state wave function, like the lo-and 20-orbitals of CO, CDAD appears due to the lack of spherical symmetry in the final state. For carbon K-shell experimental results are compared to model calculations. Investigations at the Pd core levels proved that CDAD does also arise in X-ray photoemission from non-magnetic crystals.
