Abstract: XANES spectrums of Fe3O4 have been determined by means of X-ray diffraction anomalous fine structure (XDAFS) with synchrotron radiation. The valley position of the 400 diffraction is a side of the high energy of the 220 valley position. The displacement quantity is about 1.4eV. This result shows that electronic states of two kinds of iron ions which lie in the different equivalent lattice positions in Fe3O4 are different.

Key words: electronic states, X-ray scattering
