Abstract

The kagome lattice is the most promising geometry for the discovery of quantum spin liquids – exotic quantum entangled ground states of a magnetic system. Here we propose to perform µSR experiments on a new series of rare-earth kagome antiferromagnets, A2R3Sb3O14. Some of these materials appear to show spin liquid-like behaviour, whereas others show slow spin fluctuations or an ordering transition.
