Composite gyromagnetic ferrite substrate material for LTCF phase shifter and preparation method thereof
The invention discloses a composite gyromagnetic ferrite substrate material for an LTCF phase shifter, and belongs to the technical field of electronic ceramic materials. The composite gyromagnetic ferrite substrate material is prepared by co-firing a main material LiZn ferrite and an auxiliary material strontium ferrite at low temperature. According to the invention, the main material LiZn ferrite selects an iron-deficient formula substituted by Ti < 4 + >, Mn < 3 + > and Bi < 3 + > ions, so that low-temperature sintering is ensured, and meanwhile, high saturation magnetization and low ferromagnetic resonance line width are achieved; micro-nano structure particles with high Curie temperature are selected as the auxiliary material SrM ferrite, the SrM ferrite with the structure has high sintering activity, in the low-temperature sintering process, formation of multiple compact microstructures mainly comprising fine grains is facilitated, and it is guaranteed that the material has the high remanence ratio and the high saturation magnetization intensity.
