Resonant magnetic Bragg scattering (RMBS) for several reflections has been measured at the Fe K-edge in Fe(3)O(4). The normal and magnetic X-ray absorption near-edge structure (XANES) for two types of Fe ion site (tetrahedral and octahedral) were successfully determined from the analysis of DAFS and RMBS spectra on the assumption that there was an electric dipole transition. The obtained normal XANES for the octahedral site is well explained as a mixture of Fe(2+) and Fe(3+) ions, and the characteristic feature of the magnetic XANES at the pre-edge peak is mainly contributed from the Fe(3+) ion at the tetrahedral site.
