摘要

通过水热反应合成了两种新化合物Cu3Bi(SeO3)2O2X (X = F和NO3)，它们均在具有空间基团Pmmn的正交晶系中结晶，呈层状结构，其中平面CuO4正方形通过共享角连接形成扭曲的kagome网络，而非磁性（SeO3）2-基团和Bi3+离子位于相邻的kagome层之间。磁性和热容测量结果证实，这两种化合物在低温下都表现出反铁磁有序和场诱导的自旋翻转转变，这与方解石型化合物的观察结果相似。

Two new francisite compounds Cu3Bi(SeO3)2O2X (X = F and NO3) with ferromagnetic spin-1/2 kagomé layers

Two new compounds Cu₃Bi(SeO₃)₂O₂X (X = F and NO₃) were synthesized by means of hydrothermal reaction, both crystallizing in a orthorhombic system with space group Pmmn and exhibiting a layer structure, where the planar CuO₄ squares connect to each other via corner-sharing to form a distorted kagome network, while nonmagnetic (SeO₃)^2- groups and Bi³⁺ ions are located between adjacent kagome layers. Magnetic results of magnetic and heat capacity measurements confirm that these two compounds both show an antiferromagnetic ordering and field-induced spin-flip transition at low temperature, which are similar to those observed in francisite-type compounds.
