Small-line width and low-loss microwave garnet material with an adjustable dielectric constant, and preparation method thereof
The invention discloses a small-line width and low-loss microwave garnet material with an adjustable dielectric constant, and belongs to the field of microwave ferrite materials. The chemical formulaof the material is Y3-2a-b-b-2e-f-n-kBibCa2a+c+2e+f+nVaZrcAldNbeSnfInmGenPrkFe5-a-c-d-e-f-m-n-kO12, wherein 0 <= a <= 1, 0 < b <= 1.6, 0 <= c <= 1, 0 <= d <= 1, 0 <= e <= 1, 0 <= f <= 1, 0 <= m <= 1,0 <= n <= 1 and 0 < k <= 1. The invention further discloses a preparation method of the material. The performances of the material are as follows: the ferromagnetic resonance line width delta H <= 2 kA/m, the dielectric constant epsilon is more than or equal to 15 and less than or equal to 35, and dielectric loss tg delta epsilon <= 0.0001. The material cost is low, the dielectric constant can beadjusted according to needs, the adjustment range is large, and the line width is small, the loss is low, so microwave components such as circulators and isolators of different sizes can be matched; and compared with a common material, the material of the invention as the following advantages: the size of a microwave component can be obviously reduced in the same frequency band, or under the samesize, the working frequency band can be obviously reduced, and meanwhile, the insertion loss and other properties of the component are basically the same or slightly changed.
