A series of Eu 3 + -substituted Mn 0.65 Zn 0.35 Fe 2-x x O 4 ( = 0.00-0.04) nanoscaled ferrites were synthesized by a citrate sol-gel combustion processing. The effects 3+ substitution on the crystalline formation, microstructure and magnetic properties Mn-Zn ferrite annealing at temperature from 500°C to 800°C investigated. results showed that lattice parameter increased it contributed monophase spinel with addition x≤ 0.03. remanence coercive field but changed slightly in saturation magnetization when powders 700°C.
