Abstract
We have grown a series of Fe samples on Au(111) by molecular beam epit axy. Fe was grown on Au at 30 degrees C and shows clear reflection hig h energy electron diffraction (RHEED) oscillations up to 8 monolayers, suggesting layer-by-layer growth on Au. A combined study of RHEED, me dium energy ion scattering, and x-ray diffraction scans has strongly i ndicated that Fe initially grew as fcc(111) on Au(111) below the thick ness of 3 monolayer and for the subsequent growth the Fe bcc(110) stru cture begins to form. Magneto-optical Ken effect measurement has shown that the magnetization easy axis lies in the plane of the film for th e thickness range from 3 to 20 Angstrom and there is a perpendicular a nisotropy when the thickness of Fe is about one monolayer.
