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…
