Dynamic crystallography reveals spontaneous anisotropy in cubic GeTe
Simon A. J. Kimber, Jiayong Zhang, Charles H. Liang +10
Cubic energy materials such as thermoelectrics or hybrid perovskite materials are often understood to be highly disordered. In GeTe and related IV-VI compounds, this is thought to…
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…
A neutron tomography study: probing the spontaneous crystallization of randomly packed granular assemblies
Indu Dhiman, Simon A. J. Kimber, Anita Mehta +1
We study the spontaneous crystallization of an assembly of highly monodisperse steel spheres under shaking, as it evolves from localized icosahedral ordering towards a packing reac…
Negative thermal expansion and magnetoelastic coupling in the breathing pyrochlore lattice material LiGaCr4S8
G. Pokharel, A. F. May, D. S. Parker +9
The physical properties of the spinel LiGaCr4S8 have been studied with neutron diffraction, X-ray diffraction, magnetic susceptibility and heat capacity measurements. The neutron d…
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…
