Garnet ferrite material with high dielectric constant and high Curie temperature as well as preparation method and application of garnet ferrite material
The invention relates to the technical field of microwave ferrite materials, in particular to a garnet ferrite material with a high dielectric constant and a high Curie temperature, chemical components of raw materials of the garnet ferrite material are designed according to a formula of Y < 3-x-a > Bi < x > Ca < a > Sn < a > In < y > Mn < z > Fe < 5-a-y-z-delta, x is more than or equal to 0.5 and less than or equal to 1.2, y is more than or equal to 0.01 and less than or equal to 0.1, z is more than or equal to 0 and less than or equal to 0.1, and delta is process iron deficiency. The ferrite material provided by the invention is a high-dielectric low-linewidth microwave ferrite material with the 4pi Ms of 1700-1950 Gs, the dielectric constant of 23-31 and the Curie temperature Tc of 190 DEG C or above. The microwave ferrite material has high dielectric constant and high Curie temperature, provides a basis for further miniaturization of microwave ferrite devices, and is very beneficial to research, development and production of miniaturized circulators and isolators.
