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 -... -
Thermochromism in N-salicylideneanilines
N-salicylidineanilines are known to show thermochromic behaviour, which is currently postulated to arise from an intramolecular proton shift between the keto and enol form as... -
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... -
Defect structure of oxygen-deficient Yb2Zr2O6.5
Ytterbium zirconate is of fundamental interest as a model frustrated magnet, and of potential technological importance as a thermal barrier material. In both cases oxygen... -
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... -
Single-crystal neutron diffraction studies of chain-ordered brownmillerite su...
We are performing structural investigations of a series of brownmillerites (Sr,Ca)2(Fe,Co)2O5 which display long-range modulated ordering of oxygen vacancies at ambient and high... -
Oxide ion defects distribution and conduction pathways in apatite-type silicates
Apatites are functional materials with important potential applications as solid electrolytes, and also as biomaterials, ceramics for nuclear waste immobilisation, and... -
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... -
H/D isotope effect on enamtiomers: the case of Alanine
In the current description of any molecular system based on the Schrodinger equation with a Hamiltonian accounting only for the electromagnetic forces, the structural properties... -
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... -

Martensite Variants and elastic Constants of Co-Ni-Ga Shape Memory Alloys
Pseudoelastic Co-Ni-Ga high-temperature shape memory alloys are characterized by a wide range of tunable transformation temperatures and lower processing costs compared to... -
Two-Dimensional Incommensurate Modulation in Melilite
We have prepared large single crystals of the melilite electroltyes Ln1+xCaxGa3O7+d; (Ln = La and Nd; x = 0 and 0.5) using a floating zone mirror furnace. We have characterised... -
Structural Investigations of Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 Piezoel...
Discovery and development of advanced materials requires understanding and control of the relationship between composition, structure and function. In crystalline materials,... -
Quantum Spin Ice ground states and Structural Disorder in non-Kramers rare-ea...
Pyrochlore oxides based on non-Kramers rare-earth ions, such as Pr3+ and Tb3+, are candidate materials for the formation of the Quantum Spin Ice. However, structural disorder is... -
Neutron Diffraction Studies on Double-Hydrogen-Bridged Diborane(4) Compound
The object of the proposed experiment is to definitively locate hydrogen atoms on the extraordinary short B¿B bond by single crystal neutron diffraction method. Because the... -
Wide-angle neutron scattering study of the unusual nematic-nematic transition...
An intriguing unknown variant of the nematic liquid-crystal phase (Nx) has been discovered first in a class of main-chain polymers, and later in LC dimers connected via an...
