Abstract

Electron-density analysis has been developed to make use of the intensity difference in the resonant X-ray magnetic scattering (RXMS) between left- and right-circular polarizations. The magnetic electron density was obtained at the electronic transition energy, E=7.1082keV in the Fe K pre-edge by using the difference-Fourier synthesis. Difference peaks due to magnetic electrons of Fe₃O₄ appeared in the difference-Fourier maps, where Fe ions in the B site have a pair of positive peaks of 0.36e/Å³ in height at a distance of 0.63 Å from the center. The magnetic electron densities are caused by magnetic unpaired 3d electrons in the FeO₆ octahedron, where the pre-edge peak is prohibited by the selection rule in the dipole transition with the O_h symmetry. Thus, it has led to the contribution from the quadrupole transition or the hybridization related to the A-O-B superexchange interaction among neighboring ions.
