Abstract

Epitaxial single crystalline films of iron oxides have been grown on MgO(100) substrates by means of MBE. Natural Fe or 57Fe was evaporated from alumina crucibles, and oxidized simultaneously with a dosed flux of NO2. The resulting oxide layers have been characterized in situ with RHEED, LEED, XPS, and AES. RHEED intensity oscillations, observed during deposition of the oxides, indicate a layer-by-layer growth for all substrate temperatures between 373 and 673 K. A stoichiometry analysis with CEMS, performed ex situ, shows that it is straightforward to prepare both the stable magnetite Fe3O4 and the metastable maghemite γ-Fe2O3 phases. Moreover, also all solid solutions in between these two extreme phases, i.e. Fe3-δO4 with 0
