J. Xu et al., SYSTEMATIC STUDY OF MOLECULAR-BEAM EPITAXY GROWTH AND MAGNETIC-PROPERTIES OF FE ON AU(111), Journal of applied physics, 81(8), 1997, pp. 3908-3910
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. (C) 1997 Am
