AbstractWe present measurements of the evolution with film thickness of the 3d electronic states at the Fermi energy of ultrathin Ni films. The morphology and thickness of the films is determined from x-ray photoelectron spectroscopy. x-ray photoelectron diffraction and x-ray magnetic linear dichroism using synchrotron radiation. Photoelectron angular distributions were measured using an ellipsoidal mirror analyzer. Even at submonolayer Ni coverages, the 3d electronic states exhibit bulk-like properties. This is attributed to the short screening length of electrons in metals, the localization of the 3d electrons, the similarity of the Ni and Cu ion cores, and finally the interaction with the underlying fcc periodic potential.

Magnetic Linear Dichroism

We studied the influence of photoelectron diffraction on magnetic linear dichroism and spin polarization in Co and Fe 3p photoemission excited by linearly polarized synchrotron radiation. We find a strong variation of the magnetic linear dichroism with emission direction. The spin polarization related to the spin–orbit interaction varies in a similar manner. This angular variation closely tracks that of the magnetic dichroism. In contrast, the exchange-induced spin polarization (-12+2)% does not vary appreciably with emission angle. These findings suggest that the main cause for the observed effects is the angular momentum character of the photoelectron wave.

ABSTRACTThe constructive interference between direct and indirect channels above the absorption threshold of a core level leads to a massive increase in the emission cross section leading to a phenomenon called “resonant photoemission”. Using novel magnetic linear dichroism in angular distribution photoelectron spectroscopy experiment we have tried to understand the nature of the resonant photoemission process in Gd metal. The presence of dichroism in Gd 4f photoemission intensity at a photon energy corresponding to resonant photoemission clearly demonstrates the photoemission-like nature of the resonant photoemission process.
