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

Manganese ferrite nanoparticles with in steps of 0.1 have been produced using the glycol-thermal method at 200 oC. Single-phase formation was confirmed by X-ray powder diffraction (XRD) which revealed a well-defined cubic spinel structure with space group Fd3m. structure parameters were also estimated from XRD data. Average crystallite sizes ranged from 8.91 to 9.77 nm. The Vibrating sample magnetometer measurements show that the produced nanoparticles exhibit superparamagnetics behavior at room temperature. Magnetic properties as a function of the manganese content measured at 300 K were also investigated. The Fe3+ ions distributions among tetrahedral and octahedral sites, hyperfine parameters and magnetic state of the as-prepared samples were studied using 57Fe Mössbauer spectroscopy technique.
