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... -
Neutron spectroscopy study of the C-H vibrational modes in defective graphene
We have conducted an extended study of hydrogenated defective graphene, synthesized by chemical routes (hydrogenated thermal exfoliated graphite oxide or H-TEGO), including... -
SESANS of beetle scales and butterfly wings
Neutron scattering and in particular SESANS is able to give us excellent ensemble averaging of the optical properties of materials which exhibit structural colour. We plan to... -
SESANS investigation of structural colour in polar bear hair
Structural colour arises not from dyes or pigments, but from light scattering off of the inner geometry of the material itself. This offers greater stability than standard...
