Perovskite-like layered structure compound and preparation method thereof
The invention provides a perovskite-like layered structure compound as shown in a formula Bi8Fe3-xMxTi2O20Q which is described in the specification. The invention further provides a preparation methodof the perovskite-like layered structure compound. The perovskite-like layered structure compound is different from the prior art in which only a bismuth oxide layer structure is modulated independently or the molecular design of a perovskite layer is modulated through a doping agent. According to the perovskite-like layered structure compound of the invention, a bismuth oxide layer is modulated,so that the bismuth oxide layer and a perovskite layer can form new structural units; a transition metal element is used as a doping agent to carry out magnetic ion doping on the B site of the perovskite layer to modulate the molecular design of the perovskite layer, so that the transition metal element doped perovskite-like layered structure compound has high Curie temperature, good magnetism and insulation performance, and has good potential in future energy transmission, energy conservation and other aspects.
本发明提供了一种如式BiFeMTiOQ所示的类钙钛矿层状结构化合物；本申请还提供了所述类钙钛矿层状结构化合物的制备方法。与以往只单独对铋氧层结构进行调制或者通过掺杂剂对钙钛矿层分子设计进行调制不同，本发明对进行铋氧层调制，在使得铋氧层和钙钛矿层均形成新的结构单元的同时，以过渡金属元素作为掺杂剂向钙钛矿层B位进行磁性离子掺杂来调制其分子设计，使所得过渡金属元素掺杂的类钙钛矿层状结构化合物具有高居里温度、良好的磁性和绝缘性能，在未来能量传输、节能等方面的应用具有良好的潜力。
