Study of magnetic spiral in the room temperature multiferroic BiFeO3 - PbTiO3
BiFeO3 is a room temperature multiferroic, displaying both ferroelectric and antiferromagnetic (AFE) ordering. x-BiFeO3 - (1-x)-PbTiO3 is also multiferroic at room temperature... -
The application of INS to examine high specification Fe Fischer-Tropsch catal...
Over the last 4-5 years the research team have been developing INS methodology that can be applied to investigate Fe Fischer-Tropsch (F-T) catalysts. The first stage of that... -
Low-Temperature Structural Phase Transitions in GeV4S8
The defect thiospinel, GeV4S8 adopts a cubic structure at room temperature (space group F-43m). We have identified a new monoclinic phase of this material at 2K, which may be... -
Site Dilution and Orbital Effects in Magnetically Frustrated Perovskites Ba2C...
Antiferromagnetic interactions on geometrically frustrated lattices such as the fcc lattice can result in novel magnetic states and structures. Ba2CoMoO6 is an fcc... -
QENS studies of molecular hydrogen in K-doped electrospun graphite nanofibres
The physisorptive capability of graphite-based nanomaterials for hydrogen is strongly dependent on their surface areas and nanomorphologies. We have made electrospun graphite... -
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... -
Water Binding and Solvent Dynamics in Natural Deep Eutectic Solvents
Deep Eutectic Solvents (DES) are molecular mixtures similar to ionic liquids, having melting points below room temperature. However instead of being composed of a salt, the... -
Hydrogen dynamics in clay nanotubes
We will study H2 dynamics in the nanotubular clay imogolite whose structure has an external diameter of ~2.5 nm and an inner diameter of <1 nm. The tube length of synthetic... -
The Dynamics of Molecular Hydrogen in Synthetic Clays
In this proposal we aim to study the low temperature uptake and dynamics of hydrogen in the interlayer region of partially hydrated pillared clays. There are linked dual... -
Uptake of Molecular Hydrogen by High-performance Carbon Nanostructures (IRIS)
High sorption capacities and enhanced interaction strengths are the two most fundamental prerequisites for the deployment of carbon-based materials as hydrogen-storage media. In... -
Inelastic Neutron Scattering Investigation of the Interactions Between a Meta...
We have synthesised a Co centred and an In centred MOF which represent the first examples of MOFs in which the channels are functionalized by both acidic carboxyl and basic... -
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... -
Investigations on magnetic structure and spin density wave ordering in two di...
Amongst the various layered compounds [Ca2CoO3][CoO2]1.62 (CCO) is very intriguing because of its complex crystal and magnetic structure which is yet hidden. The crystal... -
Stochastic vs. Intermolecular Motions in Strongly Associated Liquids: The Cas...
Neutron scattering is a powerful technique to study stochastic motions in liquids but it requires an energy resolution well below the meV range. As a consequence, quasielastic... -
Which is it? ¿ Neutrons distinguish monolayers xrays can¿t.
We have obtained the monolayer structure diffraction patterns from several iodoalkanes adsorbed on graphite, of interest in the study of non-covalent bonding. However, it is... -
