Abstract

The chemical reactions induced by 40 keV He+ ions in α-Fe2O3 and Fe3O4 were investigated by the conversion electron Mössbauer spectroscopy(CEMS). Magnetite(Fe3O4) was formed upon the bombardment of α-Fe2O3, whereas no change was observed in Fe3O4. The initial G value for Fe3O4 formation is estimated to be 3.5×10−4 for 100 nm depth from the surface. The application of CEMS and sputtering technique to ion bombardment chemistry is discussed.
