Low Temperature Fired Ferrite/Ceramic Composite Materials and their Permeability Spectra
Ni-Cu-Zn ferrite/CaTiO3 and Ni-Cu-Zn ferrite/BaTiO3 composites which can be applied in low temperature co-fired ceramic (LTCC) technology were synthesized by conventional solid-state reaction lower than 950°C. The complex permeability spectra of the above two composites have been investigated. The contribution of spin rotation and domain wall motion to the permeability spectra was estimated by the numerical fitting of measured data to the relevant formula. Influence of two types of magnetizing processes on the permeability of different composites has been analyzed combining with the variation of microstructures.
