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

Single phase Mg_0.5Co_0.5(RE)_0.1Fe_1.9O₄ nano-ferrites (where RE= La, Ce, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb and Lu) were successfully synthesized by glycol-thermal method from high-purity metal chlorides. The as-prepared samples were characterized by powder X-ray diffraction (XRD). The average grain sizes deduced from XRD data were found in the range 9 – 14 nm. The magnetic properties were deduced by ⁵⁷Fe Mössbauer spectroscopy and vibrating sample magnetometer (VSM). The dependence of the structural and magnetic properties are correlated with the number of the RE 4f electrons and the de Gennes factor.
