The measurements combining Kβ 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 Kβ′ 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.
