Correlation of structures, compositions and magnetism of copper-deficient lay...
This experiment will investigate three related systems which contain copper deficient anti-fluorite-type copper sulfide layers. The overall aim is to correlate magnetic and... -
Magnetic structure and multiferroicity in metal-formate perovskites
The family of guanadinium metal formates (M=Mn, Fe, Co, Ni, Cu) are isostructural with the perovskites and are therefore of interest for potential applications: in particular,... -
Superstructures in lithium cobaltate
The battery material LixCoO2 has recently been shown to have high thermopower comparable to NaxCoO2 at high x. In the case of NaxCoO2 we showed using neutron Laue diffraction on... -

High Pressure Neutron Diffraction Study of the Organic-Inorganic Perovskite P...
The organic-inorganic perovsike (OIP) methylammonium lead iodide, MAPbI3, has been identified as a promising candidate for the development of efficient solid-state solar cells.... -
Atomic structure of formamidinium lead iodide perovskite
New perovskite phases containing lead and halogens with a molecular cation are providing new options for materials in solar cells, giving unusually high efficiencies in... -
Multiferroic (Ferroelastic/Magnetic) Phase Transitions in KMnF3
KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling... -
Molecular dynamics and melting in CH3NH3PbCl3:
The organic-inorganic perovskites (CH3NH3Pb(Br,Cl,I)3) have been identified as efficient photovoltaic materials. Theoretical calculations have suggested that the low energy... -
Dynamical studies of incommensurate spin-density wave order in SrMn1-xWXO3 (X...
Our recent neutron scattering studies on SrMn1-xWXO3 exhibit rich structural and magnetic phases ranging from incommensurate charge (ICDW) and spin (ISDW) density wave... -
Is dynamic asymmetry the essential ingredient in the (universal?) 'strong-fra...
We want to elucidate whether the so-called ¿strong-fragile¿ transition reported for water mixtures is a universal phenomenon driven by confinement effects originated by the... -
Thermal expansion and phase transition in magnesium sulfate trihydrate
A recent single-crystal study determined the crystal structure of MgSO4.3D2O, and discovered that a first-order phase transition occurs when the crystal is cooled below 245 K.... -
Proton dynamics in novel organic ferroelectric materials
The vast majority of known ferroelectrics are inorganic compounds such as barium titanate and potassium dihydrogen phosphate. Contrary to naïve expectation, ferroelectricity in... -
Negative thermal expansion in the rutile phase of ZnF2
It has recently been discovered than the rutile phase of zinc fluoride shows negative thermal expansion along all three crystallographic axes. What is highly unusual about this...
