Resolving competing distortions in Ca0.4Sr0.6TiO3 using complementary electron and X-ray techniques
Robin Sjökvist, Catriona A. Crawford, Richard Beanland +1
We present a study of the perovskite Ca0.4Sr0.6TiO3 using variable temperature transmission electron microscopy (TEM) and powder X-ray diffraction (PXRD). At room temperature and b…

Signatures of Orbital Order and Disorder in Fluoro-Perovskites with Electronic Degeneracies
C. A. Crawford, C. I. Hiley, J. Gainza +3
A detailed high-resolution, variable temperature powder diffraction study of the fluoro-perovskites NaFeF and NaCoF is performed to probe their orbital ordering transitions…

Pressure-induced orbital reordering in NaCuF
Craig I. Hiley, Catriona A. Crawford, Craig L. Bull +5
The high-pressure behaviour of NaCuF is explored by powder neutron diffraction and density functional theory (DFT) calculations. A first-order phase transition is observed…
