Magnetic thin films such as iron and nickel oxides have a variety of technological applications. Iron and Nickel oxide thin films have been synthesized by the Solgel technique and spin coating method. In addition magnetic properties, Iron oxide thin films also exhibit semi conductor properties with possible electron excitation by irradiations of visible light of wavelength below 560 nm. However, low efficiency prevented incorporating iron oxide thin films in devices despite high abundance of iron. Deposition of several layers over a single layer may increase the photo currents. Iron nickel mix oxide thin films have been fabricated over fused quartz substrate. In this study we employed Extended X-ray Absorption Fine Structure(EXAFS), X-ray absorption Near Edge Structure (XANES), and the Mossbauer spectroscopy to characterize iron and nickel oxide thin films produced by spin coating and sol-gel techniques. The effect of number of layers and annealing temperatures were explored.
