Abstract

We have studied the complex structure of valence-band and core-level X-ray photoelectron spectroscopy (XPS) spectra of a geological magnetite sample (Fe₃O₄, Sverdlovsk oblast, Russia) containing Fe²⁺ and Fe³⁺ ions and impurities (Mg, Al, Si, Ti, and others). The results demonstrate that the XPS spectra of magnetite reflect a superposition of spectra of Fe²⁺ (3d⁶) and Fe³⁺ (3d⁵) ions in their high-spin states. We have evaluated the Fe 3p, Fe 3s, and Fe 2p binding energies in the different Fe ions. The measured Fe 3s spectrum of magnetite consists of two doublets with a splitting of 5.2 eV for Fe²⁺ and 6.5 eV for Fe³⁺. These values agree with results of theoretical calculations for Fe atoms by the final state configurational interaction method: 4.0 eV for Fe²⁺ (3d⁶) and 6.8 eV for Fe³⁺ (3d⁵).

期刊介绍： Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
