The complex dielectric constant and complex permeability of BaZnzCo2-zFe16O27/SiO2-paraffin wax composites had been measured. Both the complex dielectric constant and dielectric loss exhibit almost no variation with frequency in 0.1-6.0GHz. The real part of permeability decreases with increasing frequency for all samples, and the imaginary part of permeability exhibits a clear resonance peak at 1.44GHz for Co2 W/SiO2,1.32GHz for Zn0.5 Co1.5 W/SiO2, 1.20GHz for Zn0.8Co1.2 W/SiO2, and 1.08GHz for Zn1.1 Co0.9 W/SiO2. It is also showed that the content of zinc has a close effect on the magnetic properties of BaZnz Co2-zFe16 O27/SiO2 microcrystalline glass ceramics,the greater the zinc content, the higher the values of imaginary part of permeability and magnetic loss. %K BaZnz Co2-zFe16O27/SiO2 %K microcrystalline glass ceramics %K sol-gel %K microwave property
