Correlations in the spin-liquid ground state of the Ising triangular antiferromagnet NdTa7O19
A classical disordered, macroscopically degenerate ground state was predicted for the Ising triangular antiferromagnet already in 1950, while additional non-commuting exchange terms were later suggested to possibly lead to its quantum counterpart, a quantum spin liquid. Several complementary experiments that we have undertaken on a novel triangular antiferromagnet NdTa7O19 suggest that it might be the first to realize such a state. Our previous INS study has revealed that its crystal-electric-field ground-state Kramers¿ doublet is characterized by highly anisotropic Ising exchange interactions between effective spin-1/2 degrees of freedom, while our muSR study has suggested a quantum-disordered ground state with low-frequency excitations that are found to persist down to at least 66 mK. Here we propose to investigate spin correlations as a unique fingerprint of the spin-liquid ground state via magnetic diffuse scattering on the D7 spectrometer, which would allow us to further characterize and better understand this enigmatic ground state.
