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

Single phase Mg0.5Co0.5(RE)0.1Fe1.9O4 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.
