Garnet ferrite material with high dielectric constant and preparation method thereof
The invention discloses a garnet ferrite material with a high dielectric constant and a preparation method thereof. The chemical formula of the garnet ferrite material is Y3-a-b-(2c+d+e)GdaBibCa2c+d+eVcZrdSneMnfAlgFe5-c-d-e-f-g-delta O12, a is greater than 0 and less than or equal to 1.2, b is greater than or equal to 0.6 and less than or equal to 1.5, c is greater than 0 and less than or equal to0.6, d is greater than 0 and less than or equal to 0.7, e is greater than 0 and less than or equal to 0.7, f is greater than 0 and less than or equal to 0.15, g is greater than 0 and less than or equal to 0.5, and delta is greater than 0 and less than or equal to 0.3, the delta is process iron deficiency amount. The invention further provides a preparation method of the material. The garnet ferrite material with the high dielectric constant has the temperature characteristics of narrow resonance line width delta H and excellent saturation magnetization intensity Ms, can effectively reduce thesize of a central junction region of a microwave ring/isolator, and meets the miniaturization design requirement of a device.
