True symmetry of correlated Dirac and Weyl semimetal candidates CeSbSe and Ce...
We have recently performed a magnetic neutron scattering study at WISH to understand the unusual metamagnetic behaviour of the Dirac semimetal candidate CeSbSe. Unexpectedly,... -
Pressure dependence on the isomorphic phase transition in KOs2O6
We are requesting 5 days of beamtime on HRPD to measure powder diffraction patterns of KOs2O6 under He gas high pressure up to 150 MPa. KOs2O6 exhibits a novel phase transition... -
Magnetic structure of magnetocaloric manganites
Magnetic cooling has recently become the focus of cooling system technology as it boasts important advantages in terms of power consumption and for the environment e.g. not... -
Structure of multi-component mixed metal molybdates by neutron diffraction
Our general aim is to understand the defect structure of complex oxides in ternary oxide systems, which are known to be effective selective oxidation catalysts. For this purpose... -
Application of Superpace methods to long period Perovskite superstructures
Recently there have been considerable several reports of ¿nanostructured¿ perovskite oxides. In order to obtain detailed knowledge of the factors controlling the formation of... -
Competition between C-H---O hydrogen bonds and C=O----Br halogen bonds
Our main objective in this proposal is to study the competition between halogen and hydrogen bonding as a function of temperature in the complex (CH3)2C=O--- Br2. The results of... -
Investigation of the Li-intercalation mechanism for the perovskite Li0.18Sr0....
Our work on LSTN showed that it exhibits favourable electrochemical properties, i.e. rapid diffusion of lithium into the structure at low temperatures and the ability to... -
In-situ High Temperature Studies of BiFeO3 in a Stabilising Oxygen Atmosphere
The drive to find novel materials for applications such as data storage has led to a resurgence in research into multiferroic materials. Bismuth ferrite is the most widely... -
Crystal and Magnetic Structures of Ba2BTeO6 (B=Cu, Ni, Zn)
Ba2CuTeO6 and Ba2NiTeO6 are compounds with structures related to that of the proposed spin liquid Ba3CuSb2O9. The space group and nature of the B-site ordering in Ba3CuSb2O9... -
Understanding negative compressibility in KMn[Ag(CN)2]3
Negative linear compressibility (NLC) is the phenomenon whereby at least one of the linear dimensions of a material actually expand under hydrostatic pressure. It is only... -
Structure-conductivity relationship in La2-xBaxNiO4+d
Unusual total conductivity behaviour at high Ba contents may be attributed to a change in conduction mechanism at high tempertaures, structure change or phase... -
Magnetostriction in (Bi,La) orthoferrites
We have recently observed unusual magnetostrictive behaviour in Bi0.5La0.5FeO3 (BLFO), a phenomenon which is not present in either solid solution end member. This proposal seeks... -
The structures of simple halogen bridged complexes
We propose a high-resolution neutron powder diffraction study of the complexes 1, 4-dioxane X2, where X = Cl, Br, I. These are the simplest halogen-bonded complexes in which a... -
Structural Studies of PbZr1-xTixO3: completing the puzzle in the tetragonal a...
We request 6 days of HRPD time in order to study the structures on the tetragonal side of the lead zirconate-titanate (PZT) phase diagram, a region that has so far been rather... -
Neutron Diffraction Study of a Spin-1/2 Pyrochlore Lu2Mo2O5N2
Ammonolysis of R2Mo2O7 pyrochlores gives R2Mo2O5N2 containing S = ½ Mo5+. They are excellent candidate materials for investigation of quantum spin liquid phenomena and we have... -
Impact of Jahn-Teller Distortions in Sr0.5Pr0.5MnO3
We propose to use the HRPD to establish the sequence of structures, and the nature of the transitions between these, in two complex manganites Sr0.5Pr0.5MnO3 and... -
Proving the successful manufacturing of chemically-ordered L10 FeNi
The tetragonal chemically-ordered L10 FeNi phase has recently attracted significant attention for advanced permanent magnet applications due to its compelling magnetic... -
Electron localisation in vanadium hollandites
Hollandites (AxM8O16, where A is a large cation and M is a transition metal, here vanadium) have been studied for a wide range of properties, including electronic phenomena such... -
Valence Bond Glass Formation as a function of temperature and composition in ...
We request three days of beamtime on HRPD to study the crystallographic structures of six compounds containing a (distorted) frustrated antiferromagnetic lattice of Mo5+, 4d1... -
