MAGNETIC-X-RAY LINEAR DICHROISM IN THE PHOTOELECTRON-SPECTROSCOPY OF ULTRATHIN MAGNETIC ALLOY-FILMS

The magnetic structure of nanoscale alloy films has been probed using the magnetic x-ray linear dichroism in photoelectron spectroscopy. FeN i and CoFe epitaxial films were grown on Cu(001), in situ and using mo lecular beam epitaxy techniques. The magnetic x-ray linear dichroism m easurements were made at the Spectromicroscopy Facility of the Third G eneration Advanced Light Source. Because soft x-rays were used to gene rate photoemission from the 3p core levels, both elemental selectivity and magnetic sensitivity were achieved simultaneously.
