The electromagnetic properties of Ba2Co1.8Cu0.2Fe12O22 (Co2Y) and Ba3Co2Fe23.4Zn0.6O41 (Co2Z) were studied by measuring microwave scattering parameters. In the transmission spectra of Ba2Co1.8Cu0.2Fe12O22, a forbidden band emerges due to ferromagnetic resonance, and the permeability will turn to negative in the vicinity of the ferromagnetic resonance frequency. In the complex permittivity spectra of Ba3Co2Fe23.4Zn0.6O41, the negative permittivity can be obtained due to dielectric resonance. Therefore, Co2Y and Co2Z can be used to construct left-handed materials possessing negative permeability and negative permittivity simultaneously.
