Dilution of the Near-Kagome Compound Vesignieite
Vesignieite, Cu3VBa2O8(OH)2, is one of very few materials approximating a kagome spin-1/2 Heisenberg antiferromagnet, a model that is the ideal setting for novel quantum spin... -
Kagome quantum spin liquids - The case of Vesignieite
We aim to explore the groundstate of a new near-perfect S=1/2 kagome antiferromagnetic (KAFM) system using MuSR at the lowest possible temperatures. The title compound is... -
Quantum spin liquids in a frustrated spin chain
LiCuSbO4 is a new 1D S =1/2 frustrated chain compound. Chains with frustrated ferromagnetic J1 and antiferromagnetic J2 interactions are of significant interest due to the rich... -
Does the muon reach thermal equilibrium in a frustrated magnet?
The usual assumption that the muon's polarisation relaxes to zero at long times may be incorrect at high B and low T: for 5T and 30mK the Brillouin function gives P=49%. We plan... -
Quantum spin liquids: beyond Herbertsmithite
We aim at exploring the ground state of new Cu2+ S=1/2 kagome compounds, isomorphic to the now-celebrated Herbertsmithite, namely CdCu3(OH)6Cl2 and MgCu3(OH)6Cl2. Due to the...
