Magnetic properties of Cr overlayers on Fe (invited)

The magnetic properties of Cr overlayers deposited on Fe(100) were investigated by spin-resolved photoemission. Valence band spectra show a reduction of the overall polarization after deposition of Cr. Data of the Cr 3p core level show for Cr coverages up to about 2 monolayers a polarization opposite to that of the Fe 3p core level. Both findings are evidence for an orientation of the Cr moments antiparallel to the Fe moments. The core level as well as the valence band results are consistent with an average moment of about 1 µ_B per Cr atom, which is significantly smaller than calculated for a monolayer of Cr on Fe.
