摘要：

The measurements combining K resonant x-ray emission and partial fluorescence yield spectroscopy were performed for Fe metal, Fe2O3 and Fe3O4 near K absorption edge. Spin states of these materials are studied systematically with considering the origins of the Kbeta line and of the pre-edge peak. Theoretical calculations for the cluster model of Fe2O3 were performed and reproduce well the experimental emission spectra. Resonant Raman scattering effect both in the absorption edge and in the pre-edge regions was observed and compared with the theory. Chemical effects between metal and its oxides were also discussed.
