Abstract

The electrical, crystallographic, and magnetic properties of ultrathin magnetite (Fe3O4) have been studied in detail, by employing superlattice structures of Fe3O4/MgFe2O4 and Fe3O4/MgO on a variety of substrates. By careful analysis of their properties, the influence of substrate stoichiometry, Fe3O4 thin film thickness, antiphase boundaries on the magnetic properties can be separated. In particular, the controversial enhanced magnetic moment in ultrathin films (<5 nm) was confirmed to be related to the substrate stoichiometry, specifically the migration of oxygen vacancies into the Fe3O4 thin films. The multilayer concept can be employed with many other such systems and offers methods of tuning the properties of thin magnetic oxides.
