Partial substitution of Fe3+ by Sc3+ or In3+ in M-type ferrite is an effective method to tailor their anisotropy field and resonance frequency. BaMexFe12-xO19 with Me=Sc and In (0≤x≤2) was synthesized by the mixed-oxide route. XRD revealed a continuous increase of the hexagonal lattice parameters with substitution rate x. Both, the saturation magnetization and coercivity at room temperature are reduced...
The copper oxide/cobalt/carbon fiber multilayer film composites were synthesized by thermal oxidation route. In order to investigate the intrinsic reasons for microwave absorption properties of absorbers, the complex permittivity, complex permeability and the microwave absorption properties of composites were studied in the 1–18GHz range. The strongest reflectivity loss (RL) of microwave absorber...
