摘要：

Mn0.3Mg0.2Zn0.5Fe2O4 and Mn0.3Mg0.2Co0.5Fe2O4 nanoparticles with particle diameters of about 13 nm were synthesized by glycol-thermal method. The as-prepared specimens were then milled at different times up to 50 h and the single phase spinel structure confirmed by X-ray diffraction. The properties for the as-prepared and milled samples for the two systems were deduced and contrasted. Significant changes induced by milling in particle size, magnetization, coercive field and hyperfine parameters are reported. Fe-57 Mossbauer spectra at room temperature show ordered magnetic spin states in both Mn0.3Mg0.2Zn0.5Fe2O4 and Mn0.3Mg0.2Co0.5Fe2O4 by magnetization measurements.
