X-ray Absorption Spectroscopy Study of Cr Doped Fe3O4 Thin Films
碩士 === 淡江大學 === 物理學系碩士班 === 96 === We report the x-ray absorption near edge structure (XANES) study on a series of Fe-Cr-O mixed oxide thin films with nominal composition Fe1-xCrxOy (x = 0.1 ~ 0.9). Fe and Cr L2,3-edge results indicate that Cr substitute Fe3+ at B-site preferentially for x ≦ 0.3. Fo...
