Abstract

Small scale magnets have very high technological importance today. We synthesized thin film magnets containing iron and nickel oxides using sol-gel and spin coating methods. Structural properties of iron particles were investigated using Mossbauer spectroscopy, X-ray absorption spectroscopy including Extended X-ray Absorption Spectroscopy. The variation in oxidation state and other structural parameters were deduced. It appears the oxidation state of iron particles prepared by sol-gel method is very stable up to annealing temperatures of 600° C. The iron particles prepared by spin coating method exist in two different chemical environments with slightly different oxidation states.
