Abstract
Inelastic neutron scattering at temperatures below 30 K from a powder of LiZn2Mo3O8 demonstrates this triangular-lattice antiferromagnet hosts collective magnetic excitations from spin 1⁄2 Mo3O13 molecules. The excitation spectrum, that appears gapless and to extend up to 2.5 meV, remains surprisingly broad in momentum space and involves a third of the spins present above 100 K. The data are consistent with a disordered valence bond solid or a resonating valence bond state involving nearest-neighbor and next-nearest-neighbor spins.Citation
