Hexagonal crystal system gyromagnetic material and preparation method and application thereof
The invention belongs to the technical field of gyromagnetic materials, and particularly relates to a hexagonal crystal system gyromagnetic material and a preparation method and application thereof. The invention provides the hexagonal crystal system gyromagnetic material. The molecular formula of the hexagonal crystal system gyromagnetic material is CaxSr(1-x)CoyGezAlmFe(12-y-z-m)O19, wherein x, y, z and m in the formula meet the following conditions: 0.1<=x<= 0.2; 0.15<=y<=0.3; 0.2<=z<=0.4; 2.0<=m<=3.0; and 4.9<=[(12-y-z-m)/2]/(1-x)<=6. The hexagonal crystal system gyromagnetic material provided by the invention has high saturation magnetization intensity, high magnetocrystalline anisotropy internal field and low loss, so that the stability of power frequency is ensured; and meanwhile, the hexagonal crystal system gyromagnetic material provided by the invention can generate a gyromagnetic effect under the condition that an external magnetic field is not added, so that the volumes of a circulator and an isolator are reduced, and the weight is reduced.
本发明属于旋磁材料技术领域，具体涉及一种六角晶系旋磁材料及其制备方法和应用。本发明提供了一种六角晶系旋磁材料，分子式为：CaxSr(1‑x)CoyGezAlmFe(12‑y‑z‑m)O19；式中的x、y、z、m满足以下条件：0.1≤x≤0.2；0.15≤y≤0.3；0.2≤z≤0.4；2.0≤m≤3.0；且4.9≤[(12‑y‑z‑m)/2]/(1‑x)≤6。本发明提供的六角晶系旋磁材料具有高的饱和磁化强度、高的磁晶各向异性内场和低的损耗，从而保证功率频率的稳定性；同时本发明提供的六角晶系旋磁材料可以在不加外磁场的情况下产生旋磁效应，从而减少环形器、隔离器的体积、缩小重量。
