Excitation spectrum of isotope-enriched Sr2IrO4
Sr2IrO4 is an important material in condensed matter physics, having been discovered to host a novel Jeff=½ Mott insulating state.Yet while magnetic fluctuations play a crucial... -
Define the crystal structures of lead-free ferroelectric, candidate multiferr...
We have a range of new structures in the lead-free ferroelectric, candidate multiferroic and SOFC cathode areas. The HRPD data will be used to define these new crystal... -
Magnetic order in the first hybrid layered fluoroperovskites
Layered perovskites are well known functional materials but, in the context of fluoride chemistry, have so far been restricted to purely inorganic examples: K2NiF4 is the... -
Lattice dynamics in the giant barocaloric Ammonium Sulfate
Given the challenges in providing efficient and non-harmful refrigeration, it is timely to study barocaloric systems, which offer cooling power via the application of pressure,... -
Determination of the H-H bond lenght of H2/CuBTC MOF (SANDALS)
The rotational line of hydrogen is very clearly measured with TOSCA. For the past few years I have noticed that the changes in the position of the rotational line do not follow... -
High precision measurement of the spin waves in Yttrium Iron Garnet
Yttrium Iron Garnet (YIG) is a material with extremely wide ranging applications. It is a ferrimagnetic spinel with the narrowest ferromagnetic resonance linewidth of any known... -
Thermal expansion of kyanite, andalusite and sillimanite
Al2SiO5 forms three naturally-occurring polymorphs, kyanite, andalusite and sillimanite. These minerals are produced by varying degrees of metamorphism of sedimentary rocks, the... -
The effect of heat treatment temperature on the texture development of the hi...
The aim of this experiment is to measure in-situ the high temperature beta phase in a Ti and Zr alloy in order to relate the beta texture with the alpha texture observed at room... -
Thermal expansion of Mg: pre-melting effects in hcp metals and the Earth's in...
Ab initio computer simulations have suggested that pre-melting phenomena occur in the elastic properties of hcp-iron at the conditions of the Earths inner core just before... -
The partial vibrational density of states for As2Se3 glass
The method of Se isotope substitution with inelastic neutron scattering will be used to measure the partial VDOS for As2Se3 glass. This is a prototypical network forming... -
Depth-dependent diffraction of sheldonian head cores
13 carved busts have ringed the perimeter of the Sheldonian Theatre since 1669. Twice the Heads have been replaced when deteriorated beyond recognition. The second generation... -
Degenerate ground-states in Ho2-xYxSn2O7
Ho2-xYxSn2O7 is characterized by degenerate magnetic ground-states, which involve the magnetic structure for x->0 (Spin-Ice phase) and the two-fold degeneracy of the... -

Yttrium Iron Garnet (YIG) is a material with extremely wide ranging applications, having the narrowest ferromagnetic resonance linewidth of any known material. Despite decades... -
IN-SITU NEUTRON DIFFRACTION STUDIES OF METAL-HYDRIDE HYDROGEN STORAGE MATERIALS
Recently [RB 900007], we have demonstrated that it is possible to determine the detailed site-by-site behaviour of hydrogen during in-situ absorption and desorption in metal... -
Gas condensation and fluid behaviour in nanoporous ZIF-8 materials upon gate...
This proposal aims to study condensation transitions in nanoporous flexible materials by means of wide Q-range neutron diffraction. We plan to perform an in-situ gas... -
On the peculiarities of the structure of particle stabilised foam
Many formulated products pass through or end up as foams, comprising immiscible millimeter sized bubbles dispersed into an aqueous continuous phase. Frequently, surfactants or... -
In-situ diffraction studies of ammonia decomposition over iron, ruthenium and...
We request 3 days beam time on POLARIS for the in-situ study of the crystalline phase composition of iron, manganese and ruthenium catalysts for ammonia decomposition. These... -
The hypersensitivity of the water phase diagram to ammonium fluoride doping
Water displays a highly complex phase diagram that is key to a range of critical processes, from the evolution of icy moons to that of the Earth's hydrosphere and even of life... -
Multi-scale modelling of HCP alloys using peak profile analysis
Hexagonal close packed (HCP) alloys have a wide range of industrial uses, including within thenuclear industry and for aerospace applications.The properties of HCP alloys are...
