We report our investigation on structural and magnetic properties of double perovskite Sr2FeMoO6 (SFMO) films fabricated at different annealing temperatures. Structural properties have been investigated by means of X-ray absorption near-edge spectra and extended X-ray fine structure, where a change of oxidation state has been observed depending on the annealing temperature. It is found that the oxidation state becomes more deficient for a lower annealing temperature, indicating a lower number of unoccupied Fe states with decreasing Mo coordination number. Ordering degree of Fe and Mo ions in SFMO films is found to strongly correlate to the oxidation state, resulting in the subsequent magnetic property change.
