Magnetic PDF of a new potential spin liquid
The frustration of triangular antiferromagnets with isotropic interactions leads to a variety of ground states even for classical spins. In regions where several classical phases are degenerate, quantum spins may realize a quantum ground state with lower energy. From symmetry analysis, 15 different types of quantum spin liquid ground states have been classified for the triangular lattice, symmetric spin liquids as well as chiral spin liquids. Due to the lack of suitable highly symmetric compounds, such spin liquids are experimentally not much explored. Recently a new spin-1/2 triangular AFM has been synthesized, CuSb2O6 in rosiaite (PbSb2O6) structure, space group P-31m. There was no evidence of long-range order down to 1.5K, however a very steep dispersion was observed at several characteristic wave-vectors on the inelastic spectra. Since there is no long-range order in CuSb2O6 compound, we would like to approach the investigation of short-range magnetic correlations by the better suited magnetic PDF (mPDF) analysis. The mPDF will give us directly (without any modelling) an ensemble average (not a time average) of quasi-instantaneous local magnetic correlations.
