Electromagnetic properties of BaFe12O19:Ti at centimeter wavelengths

BaFe12-xTixO19 (x = 0.5, 1, 2) solid solutions were synthesized by solid state reaction at 1350 °C for pure BaFe12O19 and 1400 °C for Ti-substituted samples for 3 h in the air. The phase purity of the final products was verified by X-ray diffraction. The decrease of Curie temperature of the solid solutions from 450 to 240 °C was induced by x changes from 0 to 2. The electromagnetic parameters of the BaFe12-xTixO19 (x = 0.5, 1, 2) ferrites were measured in the frequency range of 8-12 GHz using the transmission line method.
