Abstract
A series of Eu3+-substituted Mn 0.65 Zn 0.35 Fe 2-x EuxO4 ( x = 0.00-0.04) nanoscaled ferrites were synthesized by a citrate sol-gel combustion processing. The effects of Eu 3+ substitution on the crystalline formation, microstructure and magnetic properties of Mn-Zn ferrite annealing at temperature from 500°C to 800°C were investigated. The results showed that the lattice parameter increased and it contributed to monophase spinel with the addition of Eu 3+ at x≤ 0.03. The remanence and coercive field increased with Eu 3+ substitution but it changed slightly in saturation magnetization when annealing ferrite powders at 700°C.
