Decoupling lattice and magnetic instabilities in frustrated CuMnO
Keith V. Lawler, Dean Smith, Shaun R. Evans +8
The MnO delafossites (=Na, Cu), are model frustrated antiferromagnets, with triangular layers of Mn~spins. At low temperatures (=65 K), a $C2/m \rightarro…
Spin-chain correlations in the frustrated triangular lattice material CuMnO
Simon A. J. Kimber, Andrew Wildes, Hannu Mutka +2
The Ising triangular lattice remains the classic test-case for frustrated magnetism. Here we report neutron scattering measurements of short range magnetic order in CuMnO, whic…
Effect of delithiation on the dimer transition of the honeycomb-lattice ruthenate LiRuO
Marco-Polo Jimenez-Segura, Atsutoshi Ikeda, Simon A. J. Kimber +3
The honeycomb-lattice ruthenate LiRuO is made heavily Li-deficient by chemical oxidation by iodine. The delithiation triggers a different phase LiRuO, the "D-ph…
Spin-driven symmetry breaking in the frustrated fcc magnet MnS2
Simon A. J. Kimber, Tapan Chatterji
We report the characterisation of natural samples of the cubic pyrite mineral MnS2 using very high resolution synchrotron X-ray diffraction techniques. At low temperatures we find…
A valence bond liquid on the honeycomb lattice
Simon A. J. Kimber, I. I. Mazin, Juan Shen +5
The honeycomb lattice material Li2RuO3 undergoes a dimerization of Ru4+ cations on cooling below 270C, where the magnetic susceptibility vanishes. We use density functional theory…
Giant pressure-induced volume collapse in the pyrite mineral MnS2
Simon A. J. Kimber, Ashkan Salamat, Shaun R. Evans +8
Dramatic volume collapses under pressure are fundamental to geochemistry and of increasing importance to fields as diverse as hydrogen storage and high-temperature superconductivit…
