摘要：
Fe/Bi artificially structured films(ASF's) have been prepared by alternate depositions of Fe and Bi in an ultrahigh vacuum. X-ray diffraction measurements in the small angle range confirmed the formation of periodic structures in all the samples prepared on glass substrates cooled down to about 125K. The CEMS at room temperature indicated that the samples are ferromagnetic except the one with 2 angstrom-thick Fe layers. The CEM spectra also indicated that the structure of Fe layers is amorphous when the Fe layer thicknesses are less than 15 angstrom. Magnetization measurement and CEM spectrum at 6K show that Fe monolayers in the Fe/Bi ASF are ferromagnetic.
