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... -
Pressure-induced changes in intermediate range order in the candidate polyamo...
This proposal is a continued exploration of the non-recoverable changes that have been reported in the structure of vitreous SiO2 when compressed. This proposed experiment will... -
Non-uniform elastic deformation of layered crystal structures
The aim of the experiment is to determine the relative compressibility of the structural layers in three 211 MAX phases (Ti2AlC, Ta2AlC and Cr2AlC) using the PEARL-HiPr beam... -
Phase behaviour of methane clathrate under conditions relevant to Titan's int...
Methane clathrates are likely to be an important constituent of icy satellite interiors and a source of methane in the atmosphere of Saturn's giant satellite Titan. There is... -
Neutron scattering and muSR studies of magnetic phenomena in YFe2Al10: case s...
In strongly correlated electron systems, the proximity to magnetic ordering has been of special interest. Magnetism in this class of systems is often suppressed by the Kondo... -
Spin excitations of detwinned BaFe2As2
Although spin excitations in BaFe2As2 are thought spin-wave excitations and the excitation will locate at antiferromagnetic vector (1 0) only for a detwinned sample, the real... -
Copy of: Pressure induced phase switching magnetic ordering in BiFeO3-PbTiO3
This experiment seeks to continue previous work on PEARL, whereby the phase is altered in the room temperature multiferroic BiFeO3 - PbTiO3 using hydrostatic pressure with the... -
Pressure-driven transformation of the Al coordination environment in oxide glass
In situ high-pressure neutron diffraction will be used to investigate the pressure-induced transformation of the Al coordination environment in a prototypical aluminosilicate... -
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 neutron diffraction studies of valence transitions in ACu3Fe4O12
Two new A-site ordered perovskite structure oxides, CaCu3Fe4O12 and LaCu3Fe4O12, were recently synthesized under high-pressure and high-temperature conditions in Kyoto. These... -
Inelastic Neutron Scattering study on PrRhSn3
Recently we have investigated the cubic compound PrRhSn3 using the dc and ac susceptibilities and the heat capacity. We found an evidence for the cluster-glass behavior with a... -
Determination of the crystal-electric field in geometrically frustrated pyroc...
Geometrically frustrated systems such as pyrochlore compounds receive much attention since they display exotic magnetic states. The explanation lies on the large degeneracy of... -
Equation of state of ice VI
Ice VI is likely to be a major mantle mineral in the interiors of large icy moons in our solar system, and in large icy extrasolar planets. It is also a common accessory phase... -
Phonon dynamics in liquid gallium
We propose to measure the inelastic scattering S(Q,E) maps from gallium in its liquid phases across a wide range of temperatures. This proposal is based on a new prediction for... -

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... -
High pressure phase transitions in metal-formate perovskites
The family of guanidinium metal formates has the perovskite structure and, like many perovskites, is of interest for these materials' magnetic and electric properties, in... -

Pressure-temperature phase diagram of of the Jahn-Teller transition in LaMnO3
The parent compound LaMnO3 of the hole-doped colossal magnetoresistance materials La1-xAxMnO3 (A = Ca, Sr, Ba etc.) has attracted much interest from condensed matter scientists.... -
High Pressure studies of BiMO3 perovskites
Bismuth based perovskites have been shown display many interesting properties. The field of A site bismuth perovskites gained renewed vigour due to the recent demonstration of...
