Realization of Quantum Dipoles in Triangular Lattice Crystal Ba<sub>3</sub>Yb(BO<sub>3</sub>)<sub>3</sub>

ORAL

Abstract

We investigate the thermodynamic properties of the ytterbium-based triangular lattice compound Ba3Yb(BO3)­3. These results demonstrate the absence of any long-range ordering down to 56 mK. The analyses of these results show that Ba3Yb(BO3)­3 may realize an S = ½ 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.
