| description | In this paper, a series of the gyromagnetic ferrite Li _0.43 Zn _0.26 Ti _0.12 Mn _x Fe _2.19−x O _4 (x = 0–0.14) samples were prepared with the solid-phase reaction sintering method. The influences of Mn ^3+ doping on the microscopic morphology, ferromagnetic resonance linewidth, and microwave dielectric loss of LiZnTi ferrite were investigated. Doping in an appropriate amount of Mn ^3+ will reduce the saturation magnetization of the sample and the magnetocrystalline anisotropy of the ferrite. It also inhibited the generation of Fe ^2+ and reduced the porosity, to the benefit of keeping the ferromagnetic resonance linewidth (Δ H ) of the material and microwave dielectric loss at a low level. The results suggested that when the doping amount of Mn ^3+ is 0.08, the ferromagnetic resonance linewidth of the material is 27.8 × 10 ^3 A m ^−1 , the microwave dielectric loss tangent tan δ _ε equals to 0.001, and the B-H hysteresis loop remanence ratio of the sample reaches 0.87, which is a beneficial application in lock-type microwave ferrite devices. |
