Abstract content <br> &nbsp; (Max 300 words)

Mg0.25Mn0.5Co0.25Fe2O4 and Mg0.5Mn0.25Co0.25Fe2O4 nanoferrites were synthesized by the glycol-thermal technique. X-Ray diffraction (XRD) results revealed a single phase cubic structure for both as-prepared samples with an average grain size of about 8 nm. The magnetic properties of the nanoparticles were studied using a 57Fe Mössbauer spectroscopy and Vibrating Sample Magnetometer (VSM). The samples were then annealed at 500 °C and 700 °C for 6 hrs argon atmosphere to investigate the effect of temperature on the structural and magnetic properties of the compounds. Our results show that the structure and magnetic properties depend on the annealing temperature.
