Understanding pressure-driven structural and magnetic properties in LaFeO3
This proposal is concerned with determining variations in the high pressure crystallographic and magnetic structure of LaFeO3. LaFeO3 is a characteristic example of... -
A High-Pressure Low-Temperature Crystallographic Study of the Pm3m - I4/mcm F...
The perovskite-structured phases and their associated phase transitions remain an enduring topic of study within the solid state sciences due to their importance in both applied... -
Cation ordering in silicate spinel Ni2SiO4
Silicate spinels are important minerals in the transition zone region of the Earth and in order to understand seismic signals from these depths (550-660 km) we need to know the... -
Structural and Magnetic Behaviour of PrCrO3 at High Pressure
The application of hydrostatic pressure tunes the interatomic separations within a compound, causing changes in the electronic structure. This alters many other material... -
Exploring Multiferroic Couplings in Ca2MnO4
The Ruddlesden-Popper (RP) compounds An+1BnO3n+1 exhibit a broad range of technologically interesting properties such as high-Tc superconductivity, colossal magnetoresistance,... -
Structure of hot dense liquid carbon dioxide
We propose to study the structure of liquid CO2 by neutron diffraction under high pressure and high temperatures to 6 GPa / 800 K. Carbon dioxide belongs to the most fundamental... -
Investigation of maleic-d2 acid isomerization at high pressure
Experiments performed in our laboratory indicate that maleic acid undergoes an unexpected structural change when subject to high pressure and temperature conditions. For these... -
High-pressure studies of energetic materials
This proposal seeks to identify and characterise high-pressure polymorphs of the energetic materials hydroxylammonium perchlorate, CL-20, diaminodinitroethene (FOX-7), and... -
Pressure dependence of the crystal structure of the strongly correlated bilay...
Ruthenium-oxides are important strongly correlated electron systems: the bilayer ruthenate Sr3Ru2O7 shows field-induced electronic order, while single-layer Sr2RuO4 is an exotic... -
Alloxan - a high density organic under pressure
Organic molecular crystal structures have densities that are typically in the range 1.2-1.4 gcm-3 although these can be increased, in general, to ca. 2.0 GPa through application... -

The Pressure and Temperature Dependence of the Structure of Ammonium Triiodide
We have shown that the molecular ionic solids MI3 (M=Tl, Cs, Tl, NH4) undergo structural phase transitions below 3.4 GPa at RT to give the same new high pressure phase (HP) with... -
A high-pressure study of N,N'-dimethylurea
This proposal seeks to explore the high-pressure structural behaviour of N,N¿-dimethylurea. Two new high-pressure forms have been structurally characterised using x-ray methods,... -
High-pressure structure of magnetite nanoparticles
One way in which nanoparticles may differ from bulk properties are in terms of their response to pressure, but at the present time there have been very few structural studies of... -
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... -
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... -
High pressure charge transitions in PbCoO3
PbCoO3 used to be the missing link in the PbMO3 perovskite series. PbCoO3 was recently synthesized by the Azuma group using high-pressure synthesis at 12 GPa. NPD at JPARC... -
Local ordering in the pressure-induced order-disorder transition in ammonium ...
Ammonium bromide undergoes a pressure-induced order-disorder transition, where the disordered (plastic) phase is thought to consist of a random distribution of ammonium cations...
