Ni-Cu-Zn ferrite/CaTiO_3 and Ni-Cu-Zn ferrite/BaTiO_3 composites which can be applied in low temperature co-fired ceramic(LTCC) technology were synthesized by conventional solid-state reaction at temperature lower than 950℃.Influence of the microstructures and the gap parameterδ/D on the complex permeability of the above two composites was investigated.The modifiedδ/D values of the above two composites show a good fit to the magnetic circuit model.The dielectric properties of the composites were predicted by the Maxwell-Garnctt effective medium theory and the discrepancy between measured and calculated values was analyzed.
Ni-Cu-Zn ferrite / CaTiO_3 and Ni-Cu-Zn ferrite / BaTiO_3 composites which can be applied in low temperature co-fired ceramic (LTCC) technology were synthesized by conventional solid-state reaction at temperature lower than 950 ° C. Fluidluence of the microstructures and the gap parameter δ / D on the complex permeability of the above two composites was investigated. The modified δ / D values of the above two composites show a good fit to the magnetic circuit model. The dielectric properties of the composites were predicted by the Maxwell-Garnctt effective medium theory and the discrepancy between measured and calculated values was analyzed.
