Chromium is unique amongst the d-band elemental metals in that it has a spin density wave ground state. The spin density wave is caused by Fermi surface nesting between electron...

KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling...

We will probe the structural changes as a function of temperature associated with oxide ion disorder/mobility in the end members of a redox-active oxide chalcogenide system.

We recently used high-resolution neutron diffraction on HRPD to observe the largest magneto-elastic coupling ever seen in a metallic magnet. The material studied was CoMnSi, a...

The proposed experiment is addressed to use the MARI spectrometer to study the thermal denaturation process of the psychrophile enzyme alpha-amylase in presence of bioprotectant...

We will use single crystal neutron diffraction to determine the magnetic structure of the Co2+ moments in the layered oxide chalcogenide Sr2CoO2Cu2Se2. This will enable us to...

The MIL DimimFeCl4 displays 3D antiferromagnetic ordering below 5.6K. The crystal structure at 10 K, solved by synchrotron XRPD, NPD and DFT calculations shows that it...

We propose to study by powder neutron diffraction the ordered magnetic state of the pyrochlore compound Y2Ir2O7. There is currently an increasing interest in the condensed...

High resolution powder diffraction data will be used to obtain lattice parameter and atomic coordinate variations as a function of temperature for Pr0.6Ca0.4MnO3, which has a...

20 years ago, Anderson proposed that the thermoelastic properties of the dominant (mantle) phase within the Earth, MgSiO3 perovskite, could be described as a simple Debye solid....

This proposal seeks to investigate the effect of temperature on the structures of thallium and caesium azide. High-resolution neutron powder diffraction data are necessary to...

In this proposal we aim to understand the solvation of AB by two of the most important solvents ? ammonia and THF. Neutron diffraction is a key technique in this context because...

The defect thiospinel, GeV4S8 adopts a cubic structure at room temperature (space group F-43m). We have identified a new monoclinic phase of this material at 2K, which may be...

The undecahydrate of magnesium sulfate (meridianiite) is likely to occur a major rock-forming mineral in the interiors of large icy satellites such as Ganymede, Callisto and...

Carbon blacks can be graphitised to different degrees, whereas glassy (vitreous) carbons, which are used as electrode material, in electronics and construction, and as...

Sr3Ru2O7 is a layered Ruddlesden-Popper perovskite which displays intriguing behaviour at low temperatures and high magnetic field. It can be tuned close to a quantum critical...

We request 6 days on IRIS to study the diffusion of adsorbed gas molecules (H2, CH4, C2H2, C2H4, C2H6) within a functional porous metal-organic framework (MOF) as a function of...

Ca2RuO4 is a fascinating compound, where strong electronic correlations give rise to many unique features. Just above room temperature (~360 K) the system is metallic, below the...

Ammonia Borane (AB), NH3BH3, was first synthesised in the 1950s and has now become the focus of a world wide research program with regards to its potential as a hydrogen store....

BiFeO3 is a room temperature multiferroic, displaying both ferroelectric and antiferromagnetic (AFE) ordering. x-BiFeO3 - (1-x)-PbTiO3 is also multiferroic at room temperature...
