More Information
Summary:The invention belongs to the technical field of electronic information functional ceramic materials and electronic devices, and provides a high-saturation magnetization low-temperature sintered LiZn ferrite material and a preparation method thereof. The invention aims to improve the saturation magnetization of the LiZn ferrite material so as to enable the LiZn ferrite material to adapt to phase shifters with more frequency bands, so that the microwave device can meet the trend of miniaturization, integration and high performance. According to the invention, Zn ions in LiZn ferrite are partially substituted by Zr ions to obtain the LiZn ferrite material: Li0.43Zn0.27Zr0.13Fe2.17O4. According to the LiZn ferrite material, a relatively low ferromagnetic resonance line width and a relatively low coercive force are maintained, and meanwhile, the saturation magnetization is remarkably improved and can reach up to 102.4 emu/g; Bi2O3 is adopted as a sintering aid to realize low-temperature sintering of the LiZn ferri
