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 Oh 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.
