We investigate the thermodynamic properties of the ytterbium-based triangular lattice compound ${\mathrm{Ba}}_3\mathrm{Yb}{\left(\mathrm{B}{\mathrm{O}}_3\right)}_3$. The results demonstrate the absence of any long-range ordering down to 56 mK. Analysis of the magnetization, susceptibility, and specific heat measurements suggests that ${\mathrm{Ba}}_3\mathrm{Yb}{\left(\mathrm{B}{\mathrm{O}}_3\right)}_3$ may realize an $S=\frac{1}{2}$ quantum dipole lattice, in which the dominant interaction is the long-range dipole-dipole coupling on the geometrically frustrated triangular lattice, and exchange interactions are subdominant or negligible.

三角晶格晶体Ba3Yb(BO3)3中量子偶极子的实现

我们研究了基于镱的三角晶格化合物的热力学性质 ${巴}_3镝{\left(\mathrm{乙}{\mathrm{哦}}_3\right)}_3$. 结果表明不存在任何低至 56 mK 的长程排序。对磁化强度、磁化率和比热测量的分析表明，${巴}_3镝{\left(\mathrm{乙}{\mathrm{哦}}_3\right)}_3$ 可能会实现一个 $秒=\frac{1}{2}$ 量子偶极晶格，其中主要相互作用是几何受挫三角形晶格上的长程偶极-偶极耦合，交换相互作用是次要的或可忽略不计。
