Unravelling the Interplay between Octahedral Distortions and High-Tc Supercon...
We propose elastic neutron powder diffraction experiments on perovkite bismuthates (Ca,K)BiO3. Known as one of the earliest high-Tc oxide superconductors, bismuthates have... -
Structural distortions and partial order in the selenate and chromate analogu...
The mineral mirabilite (di-sodium sulfate decahydrate) has been extensively studied by X-ray and neutron powder and single-crystal diffraction methods. The structure contains an... -
Structure and phase transitions of Sr3Ru2O7
Sr3Ru2O7 is a layered Ruddlesden-Popper perovskite which displays intriguing behaviour at low temperatures and high magnetic field. It can be tuned close to a quantum critical... -
The origin of the ferromagnetic behavior in room temperature multiferroics Bi...
The long period cycloid in multiferroic BiFeO3 influences the potential applications of this material and it has been shown that doping (with La and Mn) enlarges the cycloid... -
Crystal structures of methanol mono-ammoniate (CD3OD.ND3) and methanol hemi-a...
Mixtures of methanol with water and ammonia dominate the chemistry of cometary bodies, leftovers of the building blocks of the outer planets. We have previously determined the... -
