Negative thermal expansion in V2OPO4
Much effort has been devoted to the research of new NTE materials and the understanding of the mechanism driving this phenomenon. As part of our ERC grant on orbital... -
Simultaneous Raman and INS studies of high energy excitations in C70
The vibrational spectrum of C70 has been investigated by many techniques since it became available in significcant quantities. Previous INS spectra were recorded with small... -
Investigation of modulated crystal and magnetic structure of Ni-Pt-Mn-Ga ferr...
Ferromagnetic shape memory alloys (FSMAs) are of recent interest because they exhibit a shapememory effect that can be driven by magnetic fields. Thus, FSMAs are important for... -
Magnetic excitations in honeycomb ruthenate Na2RuO3
Honeycomb magnets with strong spin-orbit coupling (SOC) are expect to produce exotic magnetic ground states as exemplified by d5 iridates with Jeff = 1/2 state. In d4 case, SOC... -
Incommensurate-commensurate phase transitions in K2SeO4
Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such... -
Paramagnetic excitations in BaFe2As2 at high temperature
One fundamental issue in the iron-based superconductors is whether the conventional local moment Heisenberg model is sufficient to describe magnetism in these materials, or... -
In-situ reaction of lithium amide or imide with manganese(IV) oxide
We request 3 days beam time on POLARIS for in-situ powder diffraction studies of the reactions of lithium amide or lithium imide with manganese(IV) oxide under flowing argon or... -
Investigation of hydrogen dynamics on pure and metal cluster decorated metal ...
Metal oxides(MO) are widely used in technological applications especially for catalysts and supports for catalysts. We propose to use the inelastic response of H2 adsorbed on... -
Magnetic and Quadrupolar Excitations in 5d based Double Perovskites Ba2BOsO6 ...
Like the well known perovskites, the double perovskites A2BB'O6 form an enormous family of compounds exhibiting a wealth of phenomena ranging from magnetic long range order,... -
Further investigation of unusual inelastic spectrum of Ba2LuMoO6
Ba2LuMoO6 is a rare example of an s = ½ undistorted fcc frustrated system, which displays no magnetic order above T = 2 K, and thus is an excellent experimental realisation of a... -
Spin wave investigation in brownmillerite oxygen deficient perovskite Ca2Fe2O5
The Dzyaloshinskii-Moriya interaction is thought to be responsible for the stabilization of weak ferromagnetism or magnetic spiral states in a number of diverse systems. An... -
Cation ordering in silicate spinel Ni2SiO4
Silicate spinels are important minerals in the transition zone region of the Earth and in order to understand seismic signals from these depths (550-660 km) we need to know the... -
Formation and ammonia decomposition behaviour of lithium nitride hydride
Ammonia is seen as a key part of the transition to a sustainable energy economy, but needs decomposition catalysts to release its stored hydrogen. Lithium nitride-hydride... -
Simltaneous dielectric spectroscopy and neutron diffraction
We have constructed a novel microwave frequency resonator that can sit within the GEM and POLARIS diffractometers and will allow us to simultaneously collect diffraction and... -
Neutron Total Scattering Investigation of Temperature Driven Transitions in L...
This proposal is concerned with determining the local structure of LaCoO3 and observing changes within this as the material undergoes some well characterised temperature driven... -
How does a catalyst promoter affect the degree of hydrogen retention of iron-...
We have recently used INS to determine how a hydrogen pre-treatment stage of an iron based Fischer-Tropsch catalyst may modify catalytic performance. That work established how... -
Sensing SO2 in Robust Porous MOF Materials via Simultaneous Microwave Dielect...
We seek to develop new MOFs for sensing and removal of toxic gases (e.g., SO2) and request 4 days on POLARIS to study the structural binding details and dielectric data... -
The Active Site in Iron Molybdate Catalysts for Selective Methanol Oxidation
Formaldehyde is an industrially important chemical (world production 32 million tonnes in 2006) currently made from methanol using an iron molybdate catalyst. Reaction occurs at... -
Investigation of ambient temperature polarity and magnetism in the ternary so...
Pb-based materials such as PbZrxTi1-xO3 (PZT) are widely used as transducers, actuators and sensors in a range of modern technologies due to their excellent piezoelectric and... -
