The role of step-size on the pressure phase diagram of BiFeO3
bismuth ferrite (BFO) remains the most studied multiferroic as a result of room temperature electric and magnetic ordering. However, real world applications are limited due to... -
The effect of pressure on the Fe-Fe bond and carbonyl groups in Fe2(CO)9
We propose an investigation in which the crystal structure of Fe2(CO)9 will be studied as a function of pressure. This compound has previously been investigated by high pressure... -
Pressure-Induced Linkage Isomerism in a Prussian Blue Analogue
The Prussian blue analogue K0.4Fe4[Cr(CN)6]2.8.16H2O (1) is a soft ferromagnet at ambient pressure with a critical temperature (Tc) of 19 K. Bridging cyanides are oriented in... -
Structural study of BiNiO3 at high pressures and low temperatures
BiNiO3, synthesized at high pressure, has the unusual charge distribution Bi3+0.5Bi5+0.5Ni2+O3 with ordering of Bi3+ and Bi5+ charges on the A sites of a highly distorted... -
Neutronic Studies to Assess New Materials for Optimized Inverted Geometry Spe...
We request 7 days on VESUVIO to evaluate the neutronic performance of several materials used in inverted-geometry neutron spectrometers. In particular, we are interested in... -
pressure induced para-antiferromagnetic switching in the multiferroic BiFeO3 ...
We have shown using previous experiments that moderate hydrostatic pressures can be used to switch phase from tetragonal to rhombohedral in the material BiFeO3 - PbTiO3 at room... -
Towards the Calibration of Chemical Pressure
The application of hydrostatic pressure allows the precise tuning of atomic separations, which control electronic structure and virtually all the interatomic interactions that... -
High pressure structural studies of halogen bonded systems
We propose a high-pressure neutron powder diffraction study of three halogen-bonded complexes, namely trimethylamine:ICl, 1,4-dioxane:(IBr)2 and pyridine:IBr. These are some of... -
Modelling Intermolecular Interactions and Thermodynamic Properties of Naphtha...
Equations of state (EoSs) show how the thermodynamic variables of temperature, pressure and volume are inter-related. The ideal gas law, PV = nRT, is an example of an EoS which... -
Pressure response of CoMnSi: an anisotropic metamagnet with giant magnetoelas...
We wish to use elastic (this experiment) and inelastic neutron scattering (experiments on MARI and MERLIN submitted in this round) as an approach to quantify the change in... -
Understanding the "post-perovskite" structure (II): the Behaviour of CaPtO3 a...
Recently, our view of the Earth¿s lower mantle changed dramatically. It had been thought that two major phases were present throughout all of the lower mantle:... -
High-pressure, high-temperature studies of energetic materials - FOX-7, CL-20...
The aims of this proposal are to explore the high-pressure, high-temperature behaviour of 3 important energetic materials - FOX-7, CL-20, and ADN. These experiments are expected... -
High Pressure Thermoelastic Properties of Thermoelectric PbSe
We propose to study the effect of pressure and temperature on the crystal structure and the elasticproperties of lead selenide, an important material for conversion of waste... -
Unravelling the temperature-pressure phase diagram for the multiferroic, BiFeO3
Bismuth ferrite is arguably the most widely studied multiferroic material due to room temperature magnetic and ferroelectric ordering. However, despite extensive research the... -
High-Pressure Structural Behaviour of 2,2,2-trifluoro-ethanol
In the mono-alcohols (ROH) there is a competition between the packing requirements of the R-group and the demand for the hydroxyl groups to be sufficiently close for hydrogen... -
High Pressure Driven Spin States in LaCoO3
This proposal is concerned with determining variations in the high pressure structure of LaCoO3 and observing changes within this as the material undergoes some well... -
Search for magnetic ordering in the high pressure metallic state of LuNiO3 & ...
It has very recently been shown that Mott-insulators located at the crossover regime closer to the itinerant side, such as RNiO3, undergo a pressure-induced transition into a... -
Non-uniform elastic deformation of layered crystal structures
The experiment will resolve a discrepancy between earlier experiments carried out very recently by us and work elsewhere on the hydrostatic compression of a series of 211... -
Investigation of caprolactam-d11 at high pressure
High pressure has shown to be a powerful tool for the exploration of the organic solid state. In particular one is able to perform polymerisation reactions on solid materials by... -
Network compression and pressure-induced amorphisation in Zn(CN)2
Zn(CN)2 is an important material because it shows isotropic NTE over a large temperature range and to an extent more than double that of ZrW2O8. This unusual behaviour...
