Back scattered, conversion electron, Mössbauer spectroscopy was used to study oxide films formed by the thermal oxidation of iron at 225, 350, and 450 C (437, 662, and 842 F). The technique was found to be useful in the study of oxide films from approximately 50 to several hundred Angstroms in thickness without removal from the substrate. Nonstoichiometric Fe3O4, corresponding to Fe2.91O4 or a mixture of stoichiometric Fe3O4 and Ce-Fe2O3 was observed after oxidation at 225 C. Oxidation at 350 C for short times produced a duplex film consisting of Fe3O4 and α-Fe2O3, however, after oxidation at 450 C nearly stoichiometric Fe3O4 was the only oxide phase found. The absence of α-Fe2O3 in short time oxidation at 450 C was attributed to an increased cation flux at the higher temperature. Oxide growth at 225 C was studied as a function of oxidation time, and the increase in film thickness showed a logarithmic time dependence.
