Local probe study of Sr-Vesignieite

ORAL

Abstract

We discuss the results of local probe measurements (NMR and $\mu$SR) on a powder sample of $\mathrm{SrCu_3V_2O_8(OH)_2}$ (Sr-Vesignieite)[D. Boldrin and A. S. Wills, J. Mat. Chem. C 3, 4308(2015)], a spin-1/2 kagome lattice with antiferromagnetic interactions.$^{63,65}$Cu zero-field NMR and $^{51}$V NMR (in-field) reveal static magnetism at low temperatures and allow us to measure the intrinsic local susceptibility of the kagome lattice. Muon spin rotation ($\mu$SR) experiments also demonstrate static magnetism at low $T$. We discuss the possible role of the Dzyaloshinsky-Moriya interaction and the proximity of this material to a quantum critical point between ordered and quantum spin liquid phases.
