Impedance matching materials based on barium hexaferrites

The results of the study saturation magnetization and crystallographic anisotropy doped with diamagnetic ions of hexagonal ferrites are presented. It is shown that the impedance matching properties of ferrimagnetic fillers depend on equality values of magnetic and dielectric permittivity composite material in the working wave band. The contribution of the proposed replacement complexes to the magnetic and dielectric permittivity resulting materials is determined. Magnetostatic and electrodynamic properties of composites based on doped hexaferrites type M and Z are studied. Hexagonal ferrites, which play the role of an impedance matching medium in frequency range 0.1-3 GHz, are obtained. Recommendations are offered on the possibility using impedance matching composite hexagonal ferrites in the development filtering and frequency separation systems.
