Synthesis of Sr2FexMo2-xO6 (x = 0.8 to 1.5 with a step increment of 0.1) (SFMO) double perovskite oxides were done by sonochemical method at relatively low preparation temperature (950 A degrees C). Purity and existence of all elements (Sr, Fe, Mo, and O) in SFMO compound have been analyzed by energy dispersive X-ray spectroscopy (EDS). Lattice parameters and unit cell volume were studied by X-ray powder diffraction (XRD). The structural transition from tetragonal to cubic occurs around composition x = 1.1 has been noticed from XRD data. Scanning electron microscopy (SEM) confirmed grain sizes of SFMO series, which are found to be in the range of 75-185 nm. Perovskite formation has been confirmed by Fourier transform infrared spectroscopy (FTIR) spectrum analysis. Investigations of Magnetic properties have been carried out using Vibrating Sample Magnetometer (VSM) at applied magnetic field from - 20 to + 20 kOe. Saturation magnetization is found to increase from x = 0.8 to 1 and then decreases from x = 1 to 1.5, the behavior is correlated with degree of Fe/Mo ordering.
