摘要

我们研究了一个地质磁铁矿样品（Fe3O4, Sverdlovsk oblast, Russia）含有Fe2+和Fe3+离子和杂质（Mg, Al, Si， Ti等）的价带和核级x射线光电子能谱（XPS）的复杂结构。结果表明，磁铁矿的XPS光谱反映了高自旋态Fe2+ (3d6)和Fe3+ (3d5)离子光谱的叠加。我们计算了不同铁离子的fe3p， fe3s，和fe2p结合能。测量到的磁铁矿铁3s谱由两个重态组成，Fe2+和Fe3+分别为5.2 eV和6.5 eV。这些数值与用终态组态相互作用方法计算的结果一致：Fe2+ (3d6)为4.0 eV, Fe3+ (3d5)为6.8 eV。

Structure of X-Ray Photoelectron Spectra of Magnetite

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).
