摘要：

The NiCuZn ferrites were prepared by ceramic art at 900°C/2h baked and 1150°C/2h sintered. The effects of Cu2+ ion substitution and Co2+ion adulteration on the permeability of NiCuZn ferrites have been analyzed and measured at frequency band of 30-1000 MHz. The result shows that the imaginary part of complex permeability of Ni0.35-x Cux Zn0.65 CoyFe2.14O4+δ can be improved at x=0.15 and y=0.05. Base on the sample measurement results of permeability and permittivity, the calculated reflection losses R <-12 dB at 30 MHz-1000 MHz and R <-15 dB at 50-800 MHz.
