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... -
Investigating the INVAR behaviour of Pd3Fe
INVAR behaviour is the property of having zero thermal expansion over a given temperature range; something very important for certain engineering applications, and very... -

Continued studies of the temperature-pressure phase diagram of BiFeO3
Bismuth ferrite is the most widely studied multiferroic material primarily due to the observation of both room temperature magnetic and electric ordering. Despite extensive... -
The high-pressure structures of carbon dioxide hydrate
The gas hydrates offer potential as hydrogen and carbon dioxide storage materials for use either in transport applications or for carbon sequestration. We have discovered a... -
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... -
Density-driven structural transformations in magnesium silicate glass
The density-driven structural transformations in the magnesium silicate glass MgSiO3 will be investigated at pressures increasing to 17.5 GPa. This glass is one of a family of... -
Low temperature, high pressure phase transition of the Improper Ferroelectric...
We have found that the 134-perovskite, HgMn7O12 (HgAMnA3MnB4O12) exhibits improper ferroelectric coupling due to an unusual orbital ordering of the manganese cations on both... -
The phase stability of alpha-glycine at high pressure
Though the beta and gamma forms of the simplest amino acid, glycine, yield a variety of different phases on application of pressure, Raman data suggest that the most common...
