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

Mixed zinc magnesium ferrite nanoparticles Mg1-xZnxFe2O4 with 0 ≤ x ≤ 1.0 in step of 0.1 have been produced by centrifugation using the glycol-thermal method. The nanoparticles were synthesized at 200 °C using a stirred pressure reactor. Single-phase formation was confirmed by X-ray powder diffraction which revealed a well defined cubic spinel structure. According to calculations from Scherrer formula, the nanoparticles size ranged from 18 to 22 nm. The magnetic properties of the nanoparticles were studied using a 57Fe Mössbauer spectroscopy and vibrating sample magnetometer (VSM).
