Abstract The constitution, stricture and surface state of the ultrafine iron paricles pre-pared by gas evaporation technique have been investigated by means of X-ray analysis, high-resolution electron microscopy (HREM) and electron spectroscopy for chemical analysis (ESCA).The results showed that the fine paticles are spherical ones of~20nm in diameter with α-Fecores and covered by Fe_3O_4 fine crystalline layers of~4nm thickness.
