Zusammenfassung

The surface and interface structure as well as the electronic properties of thin epitaxial Fe3O4(111) films prepared by in situ oxidation of thin Fe(110) films grown on Al2O3(1120) substrates using a Mo(110) buffer layer were investigated by low-energy electron diffraction (LEED), scanning tunneling microscopy (STM),
transmission electron microscopy (TEM), and spin-polarized angle-resolved photoemission spectroscopy (SPARPES). The annealing of Fe(110) films at 700 °C in an O2 atmosphere leads to the formation of epitaxial Fe3O4(111) films. Atomically resolved STM images of the Fe3O4(111) surface show a hexagonal symmetry with 6 Å periodicity. Well-controlled interface properties at the Fe3O4(111)/Fe(110) and Fe(110)/Mo(110) interfaces were confirmed by TEM. A high spin polarization value of about 2(6065)% was found near the Fermi energy EF at room temperature by means of SPARPES with a photon energy of hv=21.2 eV. The electronic structure and spin polarization are compared to the corresponding values recently found on epitaxial Fe3O4(111) films grown on W(110) single-crystal substrates.
