High-saturation low-temperature-sintered gyromagnetic Ni-series spinel ferrite material and preparation method thereof
The invention discloses a high-saturation low-temperature-sintered gyromagnetic Ni-series spinel ferrite material. A chemical formula of the ferrite material is Ni<1-a-b-c>ZnCuCoMnFe<2-d>O<4>, wherein the value ranges of a, b, c and d are as follows: a is greater than 0.25 and smaller than 0.65, b is greater than or equal to 0.19 and smaller than 0.25, c is greater than or equal to 0 andsmaller than or equal to 0.05, and d is greater than 0 and smaller than or equal to 0.05. The high-saturation low-temperature-sintered gyromagnetic Ni-series spinel ferrite material has high saturation magnetization, low ferromagnetic resonance linewidth and low microwave dielectric loss on the premise of ensuring low-temperature sintering, and meets the application requirements for miniaturization and integration of a ring spacer through an LTCF technology.
