摘要：

Fe nanocrystalline films were prepared by the gas-deposition method (GDM). The films were composed of small particles and their aggregates. With an increase of pressure difference between an evaporation chamber and a deposition chamber, the grain size is slightly reduced and lower coercivity is realized. The Mossbauer spectra consisted of a crystalline component (alpha-Fe) and a boundary component with a hyperfine field of 310 kOe; no oxide subspectrum was observed. Magnetizations of the samples are around 95% of that of bulk alpha-Fe. Fe nanocrystals prepared by GDM are found to show good oxidization resistance. (C) 1997 American Institute of Physics.
