A位为磁性元素的三元层状MAX相材料、其制法及应用
摘要：
本发明公开了一种A位为磁性元素的三元层状MAX相材料、其制法及应用。所述三元层状MAX相材料的分子式表示为Mn+1(AzA'1‑z)Xn，M选自IIIB、IVB、VB、VIB族元素中的任意一种或两种以上的组合，A选自IVA、VA、VIA元素中任意一种或两种以上的组合，A'为磁性元素，X为C、N元素中的任意一种或两种的组合，0＜z＜1，n为1、2、3或4。该三元层状MAX相材料具有六方晶系结构，空间群为P63/mmc，晶胞由Mn+1Xn单元与(AxA'1‑x)层原子交替堆垛而成。本发明的A位为磁性元素的三元层状MAX相材料在催化、吸波、自旋电子、储能、磁制冷或者磁存储等领域具有潜在的应用前景。
摘要（英）：

The invention discloses a ternary layered MAX phase material with A site as a magnetic element as well as a preparation method and an application thereof. The molecular formula of the ternary layeredMAX phase material is Mn+1 (AzA'1-z) Xn, wherein M is selected from any one or a group of any two kinds of IIIB, IVB, VB, and VIB; A is selected from any one or a group of any two kinds of IVA, VA andVIA; A' is a magnetic element; X is any one or a combination of any two of C and N elements; z is greater than 0 and less than 1; and n is 1, 2, 3 or 4. The ternary layered MAX phase material has a hexagonal crystal structure, and the space group is P63/mmc; and the cells are formed by atomic alternate stacking of an Mn+1Xn unit and an (AxA'1-x) layer. The ternary layered MAX phase material withA site as the magnetic element has a potential application prospect in the fields of catalysis, wave absorption, spin electronics, energy storage, magnetic refrigeration or magnetic storage and the like.
