Abstract
We investigate the thermodynamic properties of the ytterbium-based triangular lattice compound ${\mathrm{Ba}}_{3}\mathrm{Yb}{(\mathrm{B}{\mathrm{O}}_{3})}_{3}$. 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 ${\mathrm{Ba}}_{3}\mathrm{Yb}{(\mathrm{B}{\mathrm{O}}_{3})}_{3}$ 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.
