Abstract
The measurements combining K β resonant x-ray emission and partial fluorescence yield spectroscopy were performed for Fe metal, Fe 2 O 3 and Fe 3 O 4 near K absorption edge. Spin states of these materials are studied systematically with considering the origins of the K β' line and of the pre-edge peak. Theoretical calculations for the cluster model of Fe 2 O 3 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.
