Microwave Absorbing Properties of CoNi Nanoparticles

摘要：

　　The CoNi alloy nanoparticles with different molar ratio of Co/Ni were prepared by the liquid-phase reduction,and the morphology and the complex permittivity and permeability of the nanoparticles were investigated by FESEM and network analyzer in the frequency range of 1~18 GHz,respectively.The reflection loss (RL) was calculated based on the determined complex permittivity and permeability.The FESEM results showed that all samples with different Co/Ni molar ratio were spherical and evenly distributed with the diameter ranging from 60 ~200 nm.Compared with other samples with different Co/Ni molar ratio,the sample with Co/Ni molar ratio of 1/2 displayed higher microwave absorbing properties due to the higher imaginary parts of the complex permittivity and permeability.
