Spin-1/2 maple-leaf lattice antiferromagnets are expected to show interesting phenomena originating from frustration effects and quantum fluctuations. We report the hydrothermal synthesis of a powder sample of bluebellite ${\mathrm{Cu}}_6\mathrm{I}{\mathrm{O}}_3{\left(\mathrm{OH}\right)}_{10}\mathrm{Cl}$ as a first potential candidate. Magnetization and heat capacity measurements reveal moderate frustration with a Curie-Weiss temperature of $–35\mathrm{K}$, and a magnetic transition at $T_N=17\mathrm{K}$. Surprisingly, the magnetic susceptibility and heat capacity above $T_N$ are well reproduced by the Bonner-Fisher model, which suggests that a one-dimensional spin correlation with a magnetic interaction of 25 K occurs in the apparently two-dimensional lattice. This emergent one-dimensionality cannot be explained by orbital ordering or dimensional reduction due to geometrical frustration. We believe that there is an unknown mechanism to cause one-dimensionality in the spin-1/2 maple-leaf lattice antiferromagnet.

包含由自旋 1/2Cu2+ 离子制成的枫叶晶格的量子反铁磁蓝碧玺

自旋 1/2 枫叶晶格反铁磁体有望表现出源自挫败效应和量子涨落的有趣现象。我们报告了蓝叶石粉末样品的水热合成${铜}_6\mathrm{一世}{\mathrm{哦}}_3{\left(哦\right)}_{10}氯$作为第一个潜在候选人。磁化和热容量测量显示居里-魏斯温度为$——35\mathrm{钾}$，以及在 ${吨}_N=17\mathrm{钾}$. 令人惊讶的是，上面的磁化率和热容量${吨}_N$Bonner-Fisher 模型很好地再现了这一点，这表明在明显的二维晶格中发生了具有 25 K 磁相互作用的一维自旋相关性。由于几何受挫，这种出现的一维无法通过轨道排序或降维来解释。我们认为在自旋 1/2 枫叶晶格反铁磁体中存在导致一维性的未知机制。
