Abstract :
In this paper, we have analyzed the dependence of magnetic properties on annealing temperature in Sr-ferrite nanoparticles were prepared by sol-gel method. Magnetic and structural properties of the powders were characterized with a Mossbauer spectroscopy , vibrating sample magnetometer (VSM), X-ray diffractometer (XRD), scanning electron spectroscopy (SEM), thermogravimetry (TG), and differential thermal analysis (DTA).
