摘要
采用缺铁配方BaZn_xCo_(2-x)Fe_(15.5)O_(27)制备W型六角铁氧体材料,并深入研究了Zn含量以及铁氧体复合物浓度对材料的微波介电特性和磁特性的影响。结果表明,通过控制Zn含量和浓度可以有效调控铁氧体介电常数的大小以及共振频率的高低,为铁氧体材料的微波应用提供了研究基础。
W-hexaferrites have been prepared using Fe-poor scheme BaZnxCo2-xFe15.5O27 The electromagnetic properties of ferrites were deeply studies by changing the substitution Zn content. The microwave performances of ferrite composites were also investigated by adjusting the concentration of fcrrite in the composites. The research results demonstrated that the permittivity and the resonance frequency of ferrites could be controlled by regulating the content of substitution Zn, and the concentration of ferrite composite deeply influenced the resonance frequency of composites. All above provide a research basis for microwave application of W-hexaferrite.
