The invention discloses a C-band ultralow-loss self-bias hexagonal gyromagnetic ferrite material, and belongs to the technical field of ferrite material preparation. The ferrite material comprises a BiCaZrVIn-YIG gyromagnetic ferrite material and a LaScBiCu-BaM hexagonal gyromagnetic ferrite material, wherein the weight ratio of the BiCaZrVIn-YIG gyromagnetic ferrite material to the LaScBiCu-BaM hexagonal gyromagnetic ferrite material is 0.1 to 10; the doping agent accounts for the weight percentage of the ferrite material, and the doping agent comprises the following components in percentage by weight: 0.3-0.7 wt% of La2O3, 0.4-0.8 wt% of SiO2 and 0.5-0.9 wt% of SrTiO3. According to the invention, LaScBiCu-BaM hexagonal gyromagnetic ferrite with high Mr/Ms and Hc characteristics is grown on the surfaces of low-loss BiCaZrVIn-YIG gyromagnetic ferrite particles, and a hexagonal gyromagnetic ferrite material with high and adjustable anisotropic field Ha, high coercive force Hc and residual magnetism ratio Mr/Ms, ultralow ferromagnetic resonance line width H and dielectric loss tan delta epsilon characteristics is developed. And the engineering requirements of low loss and wide bandwidth of the C-band miniature integrated device are met.
