Abstract

Fe 2p core‐level photoelectron spectra of magnetite were measured using soft X‐ray and hard X‐ray, and its emission angle dependence was investigated. The photoelectron diffraction pattern from different atomic sites differs because the atomic arrangement surrounding each site is different. By selecting the forward‐focusing‐peak (FFP) directions characteristic to each atomic site and measuring the kinetic energy dependence of the FFP intensities at the Fe 2p core‐level range, we succeed in detecting the variation of the peak intensity of Fe 2p core‐level spectra at different emission directions. This result, consistent with recent results, suggests that the lower‐binding‐energy peak of the Fe 2p core‐level spectrum may be assigned as the B site component.
