High-power high-dielectric-constant microwave garnet ferrite material and preparation method thereof
The invention discloses a high-power high-dielectric-constant microwave garnet ferrite material and a preparation method thereof. The chemical formula of the garnet ferrite material is Y < 3-x-y-a-b-2c > BixGdyCaa + b + 2c SnaZrb (CoGe) epsilon VcFe < 5-a-b-c-2epsilon-theta > O12, wherein x is more than or equal to 0.8 and less than or equal to 1.2, y is more than or equal to 0.01 and less than or equal to 0.5, c is more than or equal to 0.01 and less than or equal to 0.08, epsilon is more than or equal to 0.005 and less than or equal to 0.03, and theta is iron deficiency; the values of a and b meet the following conditions: 0 < = a < = 0.5, 0.15 < = b < = 0.5, and 0.15 < = a + b < = 0.5. The garnet ferrite material disclosed by the invention has high dielectric constant, low ferromagnetic resonance line width and high spin wave line width, so that the magnetic loss and power resistance characteristics of the material can be considered, and the garnet ferrite material can be used as a high-power microwave material to be applied to small-size high-power microwave devices.
