Samarium substituted cobalt ferrite Cu0.5Co0.5Fe2-xSmxO4 (x=0~0.05) powders have been prepared by a sol-gel auto-combustion method. XRD results indicate that the production of a single cubic phase of ferrites. The lattice parameter decrease and the average crystallite size also decrease with the substitution Sm3+ ions. SEM shows that the ferrite powers are nanoparticles. Room temperature Mössbauer spectra of Cu0.5Co0.5Fe2-xSmxO4 is two normal Zeeman-split sextets, which display ferrimagnetic behavior. The saturation magnetization and residual magnetization all decrease with the incorporation of the Sm3+. But the coercivity shows no significant change when the content x≤0.03, but the coercivity abruptly increase up to 1128.9 Oe when x=0.05 with the Sm3+ ions doping.
