In search of origin of metal-insulator transition in honeycomb structure Li2RuO3
Recently we have carried out inelastic neutron scattering measurements on Li2RuO3 to understand the nature of the phase transition at 550K. We have seen a clear inelastic... -
Excitations in an orbitally dimerized spin S=1 honeycomb antiferromagnet
Ru4+ ions in Li2RuO3 are on a bipartite lattice and have an orbital degeneracy. The four electrons of the magnetic Ru4+ ions in the threefold-orbitally degenerate t2g manifold...
