Abstract
The oxidation of a 9-Å-thick iron layer on MnO at room temperature has been investigated by X-ray photoelectron spectroscopy. By exposure to O 2, iron is oxidized first to Fe(II) and then to Fe(III). During the oxide formation a fast oxygen adsorption and initial oxidation to Fe(II) is followed by a slower oxygen incorporation and Fe(III) formation. After exposure to 1500 L O 2 Fe 3 O 4 seems to be formed at the surface, while the iron layer is not completely oxidized.
