The Heusler alloys Ni-Mn-Ga are widely considered as a new generation of multifunctional smart materials due to the mutual interplay between structural and magnetic properties...

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...

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...

We propose the first high P/T neutron diffraction measurements on goethite (FeOOH), both the ambient pressure alpha- as well as the high-pressure epsilon-phase, in the P/T range...

The three Al-silicate polymorphs, kyanite, andalusite and sillimanite, are well-known geological markers used to determine the extent of P- and T-induced metamorphism...

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...

The high pressure perovskite PbCrO3 has been known since the 1960’s but the electronic properties were controversial. The average structure is a cubic Pm-3m perovskite but a...

Methylammonium lead iodide has recently been recognised as an excellent photovoltaic material, with energy conversion efficient of over 20% with the prospect of gaining higher...

In situ high-pressure neutron diffraction will be used to investigate the pressure-induced transformation of the Al coordination environment in a prototypical aluminosilicate...

Magnetic superexchange is strongly dependant on the degree of orbital overlap and hence the interatomic distances and angles within a structure. One way of tuning magnetic...

Carbonate liquids are characterised by low temperature and low viscosity and play an important role in molten carbonate fuel cells, battery electrolytes and, surprisingly, in...

In an earlier high-pressure survey of the P,T phase diagram of deuterated ammonium carbonate, we observed changes in the neutron powder diffraction patterns that are consistent...

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...

The recommended method for storage of spent nuclear fuels is in an underground repository for 100,000 years. Under the long timescales, containment will fail and radioactive...

The theoretical predication of Kitaev spin liquid in honeycomb iridates triggered tremendous interests. We recently discovered a new candidate material, beta-Li2IrO3 with a 3D...

Hydrogen bonds are ubiquitous in materials across the chemical spectrum, from inorganic to biological. They influence the structure, the functionality, and therefore the...

Bismuth ferrite is arguably the most widely studied multiferroic material due to room temperature magnetic and ferroelectric ordering. However, despite extensive research the...

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...

This proposal sets out to investigate the high pressure behaviour of the double perovskitematerial with the chemical formula La2NiMnO6. The properties of this and related...

Bismuth ferrite is the most widely studied multiferroic material primarily due to the observation of both room temperature magnetic and electric ordering. Despite extensive...
