Abstract
XPS core- and valence-level spectra of various nonstoichiometric Fe3−δO4 films were measured systematically as a function of the δ value. The films were prepared epitaxially on MgO(100) substrates by NO2-assisted molecular beam epitaxy and characterized in situ with RHEED, LEED, and XPS. Stoichiometry of the films was controlled precisely by adjusting the NO2 pressure during deposition and analyzed ex situ by conversion electron Mössbauer spectroscopy.
