Abstract

This work investigates ultrasound assisted synthesis, characterization and magnetic properties of SrBaFexMo2-xO6 (x=1.0, 1.1, 1.3 and 1.4) double perovskites. X-ray diffraction (XRD) analysis confirmed proposed that samples are in single phase. It was found that lattice constants decrease with increase in composition x. Morphology of all samples was examined by Scanning Electron Microscopy (SEM) images. Energy Dispersive X-ray Spectroscopy (EDS) data confirmed purity and nonexistence of foreign elements in prepared samples. Fourier transform infrared spectroscopy (FTIR) studies revealed formation of perovskite structure. It was noticed that Fe-Mo degree of ordering decreases with an increase in composition x. Saturation magnetization of prepared samples decreased with increase of composition x, which is correlated with Fe-Mo degree of ordering.
