Static and dynamic magnetic properties of Co2Z barium ferrite nanoparticle composites
نویسندگان
چکیده
The static, dynamic and attenuation properties of Co2Z barium ferrites and Co2Z composites have been studied. The results showed that both static and dynamic magnetic properties are significantly different for large particles and nanoparticles. As compared to large particles, Co2Z nanoparticles have a small saturation magnetization Ms , large coercivity Hc , small permeability μ0 and μ ′′ max, but high resonance frequency fR . The maximum reflection loss predicted is much smaller for nanoparticles than for large particles. Therefore, Co2Z barium ferrite with large particle is more suitable for EM materials with high attenuation and broad bandwidth at microwave frequency.
