摘要：
Ultrafine particles of alpha-Fe have been studied by use of Mossbauer spectroscopy. The spectra contain a magnetically split component with broad lines which can be attributed to surface atoms. The average magnetic hyperfine field of this component decreases much more rapidly with temperature than that of the alpha-Fe core.
