摘要:	In a previous report, we showed that a series of single-crystalline iron–nickel oxide alloy thin films, with various Fe–Ni concentration ratios, could be fabricated by a molecular beam epitaxy technique. With x-ray diffraction and adsorption studies, the distribution of Fe and Ni in these compounds are found different from a bulk Fe 2 NiO 4 Fe2NiO4 ferrite phase. We extend the study to a more detailed x-ray adsorption on oxygen K edge from these films. The new results again support the model of the unique ionic distribution in these ferrite alloy films. It further reveals a detailed hybridized feature with transition metald and sp bands, which is sensitive to the local structure and near neighbors of Fe and Ni. This precisely characterized ionic structure can be directly compared to a local magnetic moment theory. A preliminary result of the magnetic response from these films is discussed.
