Inelastic neutron scattering for temperatures below 30 K from a powder of LiZn2Mo3O8 demonstrates this triangular-lattice antiferromagnet hosts collective magnetic excitations from spin 1/2 Mo3O13 molecules. Apparently gapless (\Delta < 0.2 meV) and extending at least up to 2.5 meV, the low energy magnetic scattering cross section is surprisingly broad in momentum space and involves one third of the spins present above 100 K. The data are compatible with the presence of valence-bonds involving nearest-neighbor and next-nearest-neighbor spins forming a disordered or dynamic state.

Inelastic neutron scattering for temperatures below 30 K from a powder of LiZn2Mo3O8 demonstrates this triangular-lattice antiferromagnet hosts collective magnetic excitations from spin 1/2 Mo3O13 molecules. Apparently gapless (\Delta < 0.2 meV) and extending at least up to 2.5 meV, the low energy magnetic scattering cross section is surprisingly broad in momentum space and involves one third of the spins present above 100 K. The data are compatible with the presence of valence-bonds involving nearest-neighbor and next-nearest-neighbor spins forming a disordered or dynamic state.
