Title

Spin excitation spectra in the kagome candidate material Y3Cu9(OH)18OCl8

Abstract

Recently, unusual low-temperature properties have been found in the frustrated magnet Y3Cu9(OH)18OCl8. It is argued, that the copper ions in this system build a kagome lattice with an antiferromagnetic in-plane coupling. The magnetic properties have been investigated with bulk thermodynamics, muon spin relaxation and neutron diffraction experiments. Based on these studies, there is no sign of any long-range magnetic ordering down to 20 mK. Therefore, the material might be in a quantum spin liquid state at low temperatures similar to Herbertsmithite, which we would like to further explore by inelastic neutron scattering.
