Notes:
We have grown a series of Fe samples on Au(111) by molecular beam epitaxy. Fe was grown on Au at 30 °C and shows clear reflection high energy electron diffraction (RHEED) oscillations up to 8 monolayers, suggesting layer-by-layer growth on Au. A combined study of RHEED, medium energy ion scattering, and x-ray diffraction scans has strongly indicated that Fe initially grew as fcc(111) on Au(111) below the thickness of 3 monolayer and for the subsequent growth the Fe bcc(110) structure begins to form. Magneto-optical Kerr effect measurement has shown that the magnetization easy axis lies in the plane of the film for the thickness range from 3 to 20 Å and there is a perpendicular anisotropy when the thickness of Fe is about one monolayer. © 1997 American Institute of Physics.
