Description
Microwave radiation in the GHz is increasingly being used in telecommunication and data processing. However, this has given rise to electromagnetic wave interference (EMI). Ni-Zn-Cu ferrite film was prepared by aerosol deposition method (ADM) depending on its capability as an absorber or a conducted noise suppressor in the quasi-microwave frequency range. The ADM is a kind of high-speed coating method. The film thickness of 7μm was obtained by the deposition for 4min and the rate was estimated at 2.8μm/min. The saturation magnetization of the film was 6.33x10-5Wbm/kg and the coercivity was 0.94kA/m. This value was nearly equal to that of sintered sample. The maximum complex permeabilities μ' and μ'' were 200 and 70. The resonance frequency fr=200MHz was over Snoek's limit
