Investigation of a potential triangular quantum spin-liquid

Abstract: The frustration of triangular antiferromagnets with isotropic interactions leads to a variety of ground states even for classical spins.Forconstellations of exchange parameters where several classical phases are degenerate, quantum spins may realize a quantum spin liquidstate with lower energy.From symmetry analysis, 15 different types of quantum spin liquid ground states have been classified for thetriangular lattice. Recently a new spin 1/2 triangular antiferromagnet has been synthesized, CuSb2O6 in the metastable trigonal rosiaite structure.It displays neither long-range magnetic order nor glassy freezing down to 1.5K and has dominantly antiferromagnetic correlations.Preliminary IN5 spectra show spin-liquid like steep excitations out to 7meV, and spinon-like lobes below 1 meV.We would like to study the low-energy range of the spectra on LET at dilution temperatures.
