Mapping the structural transitions controlled by the trilinear coupling in Ca3-xSrxTi2O7
Marie Kratochvilova, Fei-Ting Huang, Maria-Teresa Fernandez Diaz +7
We present the results of the high-temperature neutron and x-ray diffraction experiments on the Ca3-xSrxTi2O7 (x = 0.5, 0.8, 0.85, 0.9) compounds. The ferro- to paraelectric transi…
Properties of CO clathrate hydrates formed in the presence of MgSO solutions with implications for icy moons
E. Safi, Stephen P. Thompson, Aneurin Evans +6
There is evidence to suggest that clathrate hydrates have a significant effect on the surface geology of icy bodies in the Solar System. However the aqueous environments believed t…
Spontaneous structural distortion of metallic Shastry-Sutherland system DyB4 by quadrupole-spin-lattice coupling
Hasung Sim, Seongsu Lee, Kun-Pyo Hong +10
DyB4 has a two-dimensional Shastry-Sutherland (Sh-S) lattice with strong Ising character of the Dy ions. Despite the intrinsic frustrations, surprisingly, it undergoes two successi…
In situ apparatus for the study of clathrate hydrates relevant to solar system bodies using synchrotron X-ray diffraction and Raman spectroscopy
Sarah J. Day, Stephen P. Thompson, Aneurin Evans +1
Clathrate hydrates are believed to play a significant role in various solar system environments, e.g. comets, and the surfaces and interiors of icy satellites, however the structur…
Re-entrant Structural Phase Transition in a Frustrated Kagome Magnet, Rb2SnCu3F12
Lewis J. Downie, Stephen P. Thompson, Chiu C. Tang +2
Rb2SnCu3F12 has been studied using synchrotron powder X-ray diffraction, powder neutron diffraction and single crystal X-ray diffraction at a range of temperatures (100 to 500 K).…
Photoluminescence in amorphous MgSiO_3 silicate
S. P. Thompson, J. E. Parker, S. J. Day +2
Samples of amorphous MgSiO_3 annealed at temperature steps leading up to their crystallisation temperature show a rise in photoluminescence activity, peaking at ~450C. The photolum…
Non-aqueous formation of the calcium carbonate polymorph vaterite: astrophysical implications
Sarah J. Day, Stephen P. Thompson, Julia E. Parker +1
We study the formation of calcium carbonate, through the solid-gas interaction of amorphous Ca-silicate with gaseous CO2, at elevated pressures, and link this to the possible prese…
Carbonate Formation in Non-Aqueous Environments by Solid-Gas Carbonation of Silicates
S. J. Day, S. P. Thompson, A. Evans +1
We have produced synthetic analogues of cosmic silicates using the Sol Gel method, producing amorphous silicates of composition Mg(x)Ca(1-x)SiO3. Using synchrotron X-ray powder dif…
Complex room temperature ferrimagnetism induced by zigzag oxygen-vacancy stripes in Sr3YCo4O10.72
D. D. Khalyavin, L. C. Chapon, E. Suard +4
The high temperature ferromagnetism in Sr3YCo4O10+delta perovskite, whose origin has been the subject of a considerable debate, has been studied by neutron powder diffraction and s…
