The stoichiometries of these thin films were controlled by varying the growth rate and oxygen partial pressure. Selective growth of γ-Fe2O3 and α-Fe2O3 was achieved by controlling the growth conditions in conjunction with the choice of appropriate substrates. Growth of the iron oxide epitaxial films on MgO at ≥350 °C is accompanied by significant Mg outdiffusion. The FeO(001) film surface exhibits a (2 × 2) reconstruction, which is accompanied by a significant amount of Fe3+ in the surface region. Fe3O4 (001) has been found to reconstruct to a structure. γ-Fe23 (001) film surface is unreconstructed. Copyright © Materials Research Society 1998 Gao Y. P.O.
