High-coercivity low-loss composite hexagonal ferrite material and preparation method thereof
The invention discloses a high-coercivity low-loss composite hexagonal ferrite material and a preparation method thereof, and belongs to the technical field of ferrite material preparation. The composite hexagonal ferrite material comprises a main formula and a doping agent, wherein the main formula comprises BaCO3, ZnO, CoO and Fe2O3; the additive is prepared from Bi2O3, H3BO3 and SiO2. The W-type and M-type composite hexagonal ferrites with an exchange coupling effect are synthesized in one step, so that the coercive force of the composite hexagonal ferrites is greatly improved, and the quasi-plane characteristic of a microwave device is favorably realized; the W-type and M-type composite hexagonal ferrites with low ferromagnetic resonance line width characteristics are obtained by optimizing the additive ratio and the process, so that the insertion loss of a quasi-planarization device is reduced, and engineering application is realized. Therefore, the hexagonal ferrite material disclosed by the invention has the characteristics of high and adjustable magnetocrystalline anisotropy field, high remanence ratio, high coercive force and relatively low ferromagnetic resonance line width.
