Effect of Copper on the Structure and Properties of Manganese Zinc Ferrites

摘要

The effect of copper ions on the crystal structure, porosity, and properties of the Mn_0.6-xCu_xZn_0.3Fe_2.1O_4-γ(0≤x≤0.6) ferrites synthesized at 950 deg. C, sintered at 1300 deg. C, and cooled in a pro- Tective gaseous environment was studied by x-ray diffraction, magnetic measurements, microstructural analy- sis, gravimetry, and nuclear magnetic resonance. The change states of all cations and their distribution over the Octahedral and tetrahedral sites of the spinel structure were identified. The optimum copper content was found At which high-quality materials characterized by high magnetic induction and low electromagnetic losses can Be produced.
