muSR characterisation of the first fully-organic triangular-lattice quantum spin liquid

DOI

The most successful recipe to date for making a quantum spin liquid (QSL) is a triangular lattice of molecular-dimer radicals tuned to behave as a weak Mott insulator. Two previous examples use dimers of BEDT-TTF molecules and a further example uses dimers of Pd(dmit)2 molecules. Recently another QSL has joined this list. This new system is based on dimers of cat-EDT-TTF, an asymmetric modification of BEDT-TTF. It has some unique properties, such as dimer spins being produced by charge transfer to hydrogen atoms, which in turn provide coupling between the layers via hydrogen bonding. It is also the first fully-organic triangular-lattice QSL, with no metal atoms anywhere in the structure. We propose to use ZF, LF and TF muSR to characterise this novel QSL and compare its properties with those of the earlier examples
