From giant magneto-elastic coupling to negative thermal expansion
We recently used high-resolution neutron diffraction on HRPD to observe the largest magneto-elastic coupling ever seen in a metallic magnet. The material studied was CoMnSi, a... -
Crystal symmetry change at the magnetic transition in MnB and FeB compounds p...
The "magnetocaloric effect" (MCE) is based on the entropy difference encountered when themagnetic state of a material is changed and it can be used for refrigeration. However,... -
Improper ferroelectricity in hexagonal tungsten bronzes
Ferroelectrics are an important class of materials in modern electronics. Their application range from simple capacitors to ultrasonics transducers and sensors to memory... -
Nuclear Dynamics in Methylammonium Lead Iodide, One Atom at a Time
Methylammonium lead iodide is currently one of the most promising materials for solar energy applications, with light-conversion efficiencies exceeding 20%. Although insightful,... -
Crystal structure and thermal expansion of acetylene (C2D2)
Acetylene is produced in great abundance in the solar system wherever carbonaceous solids are exposed to energetic radiation. It has been the subject of several studies,... -
The high temperature phases of multiferroic YMnO3
Hexagonal YMnO3 is a well-studied, but poorly understood, multiferroic material, which adopts the 'geometric' mechanism of ferroelectric distortion, rather than the more normal... -
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... -

Neutron analysis of the structure of SrAl2O4 from 300 to 1273 K.
SrAl2O4 is a stuffed tridymite that has attracted a good deal of interest, since doping with Eu2+ leads to a material with elastic-luminescent response. The structure and phase... -
Structural studies of the KSbO3-type osmates Sr6Os6O19 and Bi3Os3O11
Osmium-based oxides show a wide range of interesting properties due to the variety of oxidation states osmium can adopt combined with 5d electrons displaying strong spin-orbit... -
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... -
High resolution studies of P2-type sodium ion battery cathode materials
We request 2 days beam time on HRPD for ex-situ, room temperature, powder diffraction studies of P2-type sodium-ion battery cathode materials based on the Na2/3Mn2/3Ni1/3O2... -
