我们成功地用拓扑化学方法合成了一种超高聚体反铁磁体，其中自旋形成了一个三维（3D）角共享三角形网络。磁化率和热容测量显示在。虽然没有发现伴随转变的任何结构畸变的证据，但低温磁热容显示出几乎依赖，这表明在三维超戈梅晶格中实现了二维类磁振子激发。
We have successfully synthesized a hyperkagome antiferromagnetby a topochemical method, whereions withspins form a three-dimensional (3D) corner-sharing triangle network. Magnetic susceptibility and heat capacity measurements revealed an antiferromagnetic transition at. Although no evidence was found for any structural distortion accompanying the transition, the low-temperature magnetic heat capacity showed a nearlydependence, suggesting the realization of a 2D magnonlike excitation in the 3D hyperkagome lattice.
