The constitution,structure and surface state of the ultrafine iron particles prepared by gas evaporation technique have been investigated by means of X-ray analysis,high-reasolution electron microscopy(HREM)and electron spectroscopy for chemical analysis(ESCA).The results showed that the fine particles are spherical ones of～20 nm in diameter with α-Fe cores and covered by Fe_3O_4 fine crystalline layers of～4 nm thickness.
