Doping Effect of W6+ Ions on Microstructural and Magnetic Properties of Mn-Zn Ferrites
Mn-Zn ferrites with different doping contents of W6+ ions were prepared by using standard ceramic technique.The microstructure and magnetic properties of the as-prepared Mn-Zn ferrites were investigated.It was found that all the samples with different contents of W6+ ions consisted of ferrite phase of typical spinel cubic structure.With increasing doping content of W6+ ions,the lattice constant of the ferrites decreased but the grain size increased.Through the measurement of magnetic properties,it was revealed that the saturation magnetization and initial permeability of the samples increased with small doping content of W6+ ions but decreased with additional doping,and the Curie temperature decreased monotonously with W6+ ion doping.
