The in-plane to out-of-plane spin-reorientation phase transition of ultrathin Fe on Gd (0001) has been measured recently.@footnote 1@ Theoretical work has indicated the need for six-fold symmetry of the ultrathin Fe film in order to fit existing data on the spin-reorientation phase transition.@footnote 2@ Fe films consisting of 1.5 atomic layers on bulk Gd do no exhibit any long range ordering as determined by low energy electron diffraction. Angle resolved Auger electron spectroscopy (ARAES) will be used because it is sensitive to local order on the atomic scale and will determine the local symmetry of the Fe atoms. ARAES spectra will be shown that demonstrate the extent of six-fold symmetry in these films. @FootnoteText@ @footnote 1@ C.S. Arnold et al., Phys. Rev. Lett. 83, 3305 (1999). @footnote 2@ A.P.
