Effects of Eu3+ Substitution on Nanosized Mn-Zn Ferrite Powders Synthesized by Combustion Processing
A series of Eu3+-substituted Mn0.65Zn0.35Fe2-xEuxO4 (x=0.00-0.04) nanoscaled ferrites were synthesized by a citrate sol-gel combustion processing.The effects of Eu3+ substitution on the crystalline formation,microstructure and magnetic properties of Mn-Zn ferrite annealing at temperature from 500℃ to 800℃ were investigated.The results showed that the lattice parameter increased and it contributed to monophase spinel with the addition of Eu3+ at x ≤ 0.03.The remanence and coercive field increased with Eu3+ substitution but it changed slightly in saturation magnetization when annealing ferrite powders at 700℃.
