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... -
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... -
Long-range cationic ordering in metal-organic perovskite solid solutions
The structure of the metal guanadinium formates is analogous to perovskite; the Cu compound is of particular interest as a potential multiferroic. We have recently demonstrated... -
The Structure of the High-Energy ¿Paramagnon¿ Excitations in La2-xSrxCuO4
A major problem in physics is the identification of the mechanism of high-temperature superconductivity. Many theories purport to explain the high-Tc phenomenon. In most... -
Detailed characterisation of metastable phase fractions in ZrW2O8
Cubic alpha-ZrW2O8 is the classic example of a material exhibiting the unusual property of negative thermal expansion (NTE). Despite this effect having been discovered 20 years... -
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... -
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... -
Structural studies of iridium hydrides. Part 2.
Oil is currently the primary raw material for all the carbon containing chemicals we take for granted and which are necessary for our modern life: pharmaceuticals, plastics,... -
Anisotropic Displacement Parameters and Diffuse Scattering in Graphite
The accurate description of van-der-Waals forces within DFT is currently one of the most active areas of research in computational physics and chemistry. In the case of soft... -
Short range order in triglycine sulphate above the phase transition temperature
We want to better understand the intermolecular interactions in deuterated triglycine sulphate (DTGS). DTGS is a hydrogen bonded ferroelectric with a second-order, order... -
Temperature Dependent Neutron Diffraction Studies on the Phase Transition in ...
Eu2AuGe3 was synthesized by metal flux method. Room temperature single crystal XRD data shows that this compound crystallizes within the orthorhombic Ca2AgSi3 type structure....
