Structure-property relationships in new oxide ion conductor Ba3NbWO8.5
Oxide ion conductors have been a focus of intense research due to their application as electrolytes in solid oxide fuel cells. The currently used materials (yttria-stabilised... -
A single-crystal diffuse scattering study of Ferrocene
We propose here a detailed study of the diffuse scattering of ferrocene with the key objective of investigating the origin of the cyclopentadienyl (Cp) ring disorder in this... -
Single Crystal Investigations of Polymorphism and Disorder in CH3NH3PbI3
Photovoltaics are one of the most promising technologies for meeting future energy requirements. CH3NH3PbI3 was first used in a solar cell in 2009, which gave an efficiency of... -
Crystal and magnetic structure of the polar ferrimagnet BaCaFe4O7
Polar or non-centrosymmetric ferri(-o)magnets offer a plethora of potential technological devices; the inherent magnetoelectric effect can underpin both pyroelectric or... -
The charge-ordered superstructure of YbFe2O4
There has been much recent interest in the so-called ¿novel¿ or ¿type-II¿ multiferroics, in which electrical polarisation appears at the onset of a particular type of magnetic... -

Do defect structures in the pyrochlore Tb2Ti2O7 control hidden order or the t...
The rare earth pyrochlores have been at the forefront of research into exotic magnetic phenomena for some years. In general they are of interest because they are frustrated -... -
Atomic resolution holographic study of polycrystalline yttrium hydride
It is commonly accepted that the recording of holograms with atomic resolution requires singlecrystalline samples. Closer analysis, however, shows that the reduced information... -
Diffuse scattering study of single crystal PrBa2Cu3O7-x
Standard diffraction studies of PrBCO and YBCO show that these two compounds are isostructical. However, if any Pr/Ba disorder is present in PrBCO, the diffuse scattering signal... -
Explore the spectrum of spin excitations in non-superconducting BaFe1.8Ni0.1C...
Recently, our neutron scattering experiments on electron doped BaFe2-xNixAs2 and hole doped Ba1-xKxFe2As2 suggest that the presence of both high-energy spin excitations giving... -
Defects and spin correlations in yttrium-doped spin ice
Excitations in spin ice fractionalize into de-confined magnetic monopoles that interact with each other via the magnetic Coulomb interaction. Substituting rare earth ions with... -
Magnetic Structure and Martensite Twin-Laws of ferromagnetic Co2-Ni-Ga and Fe...
Pseudoelastic, ferromagnetic Co2NiGa type high-temperature shape memory alloys (HT-SMAs) are characterized by a wide range of tunable transformation temperatures and lower... -
Multiple Coulomb phase in CsNiCrF6
The compound CsNiCrF6 hosts multiple Coulomb phases. A Coulomb phase is a material in which a relationship can be identified between some part of the material's structure and a... -
Single-Crystal Neutron Diffraction Study on [U(C5Me5)2(H)(mu¿H)]2
To our knowledge, the length of the U¿H single bond has never been accurately measured, at least not in a molecular compound by single-crystal neutron diffraction. We currently... -
Identifying hydrides in a rhenium hydroborylation catalyst
The characterization of complexes that act as catalysts for chemical transformations is an important feature in the development of new methods of use to a sustainable chemicals... -
Anomalous magnetism in oxygen-deficient scandium-doped spin ice
Our previous diffuse neutron scattering experiment on SXD showed that oxygen vacancies are the dominant defects in spin ice. The substitution of tetravalent titanium by... -
Oxygen-deficient quantum spin ice
In quantum analogues of the spin ice materials quantum mechanical tunneling between ground states is expected, and exotic emergent behaviour has been predicted including a Higgs... -
Characterisation of diffuse scattering in β-Ti GUM metal
The goal of this proposal is to measure the diffuse scattering in Beta-Ti Gum Metal. We have measured the phonon dispersion curves and have found several soft-phonon anomalies... -
Structural Studies of 9-methyltriptycenes
We aim at obtaining reliable structural information for selected compounds from a series of four 9-methyltripticene derivatives. These compounds form in the solid state... -
A combination study of the antiferromagnetism and diffusive magnetic scatteri...
As far as we know there is no single crystal neutron study on ErPr_2Si_2 yet, mainly due to fabrication difficulties. We have grown large (diameter: 6 mm; length: 8 mm) single...
