The local magnetic and electronic structures of chromium substituted iron oxide polycrystalline samples are investigated via Fe L-edge x-ray absorption near-edge structural and magnetic circular dichroism measurements.A strong dependence of atomic magnetic levels on the applied external magnetic field is observed.The magnetic behavior of Cr-doped iron oxides are determined to be dominantly governed by the d-d hybridization between Fe and Cr valence levels.In addition,the formation of CrO_(2) and Cr_(2)O_(3) chromium oxide clusters in the sample are observed to determine the magnetic ordering,i.e.anti-ferromagnetic or ferromagnetic with the changing external magnetic fields.The results highly agree with the previous studies.
