Abstract

XPS core- and valence-level spectra of various nonstoichiometric Fe_3−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.
