Single phase Mg<sub>0.5</sub>Co<sub>0.5</sub>(RE)<sub>0.1</sub>Fe<sub>1.9</sub>O<sub>4</sub> 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 <sup>57</sup>Fe 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.
