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

Mg1-xZnxFe2O4 nanoparticles ( 0<x<1 in steps of 0.1) have been produced by centrifugation using the low temperature glycol-thermal method at 200 C. Single-phase formation was confirmed by X-ray powder diffraction which revealed a well-defined cubic spinel structure with space group Fd3m. The crystallite size of the compounds ranged from 10.6-22.2 nm. A strong correlation was found between X-ray density and Zn-concentration (x). The magnetic properties as a function were investigated by using a 57Fe Mössbauer spectroscopy and magnetization measurements using vibration sample magnetometer at room temperature. The results show Zn-concentration induced transformation from paramagnetic state to magnetic ordered for x<0.8 for the studied nanosized samples.
