Abstract

We investigate the thermodynamic properties of the ytterbium-based triangular lattice compound Ba3Yb(BO3)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 Ba3Yb(BO3)3 may realize an S=12 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.
