 Abstract: The structural and magnetic properties of Fe films grown by molecular beam epitaxy on Cu3Au(001) and on Pd(001), and of Fe films in a [Fe(15Å)/Pd(40Å)]30 multilayer, have been determined by electron diffraction(RHEED, LEED), X-ray diffraction, 57Fe Mössbauer spectroscopy (CEMS), or SQUID magnetometry. Very thin Fe films are found to have a tetragonally compressed fcc (fct) structure and an enhanced saturation hyperfine field relative to that of bulk bcc Fe. The Fe magnetization in the Fe/Pd multilayer is remarkably enhanced with respect to that of bulk bcc Fe. Our results demonstrate that thin fct Fe films in these systems are in a ferromagnetic high-moment state with an Fe atomic volume (or Wigner-Seitz radius) which is rather close to that of bulk bcc Fe due to lattice relaxation.
