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... -
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... -

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... -
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... -
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... -

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... -
High-Energy dynamics and search for a continuum in CaFe2O4
We propose to investigate the high-energy (above 10 meV) excitations using either the MERLIN or MAPS chopper instruments. CaFe2O4 is interesting for several reasons. First, it... -
Search for structural modulation lifting the orbital degeneracy in triangular...
This proposal is part of our research programme on spin and orbital order in frustrated systems. AgNiO2 has a layered crystal structure with Jahn-Teller active Ni3+ ions forming... -
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... -
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... -
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... -
A High-Pressure Low-Temperature Crystallographic Study of the Pm3m - I4/mcm F...
The perovskite-structured phases and their associated phase transitions remain an enduring topic of study within the solid state sciences due to their importance in both applied... -
The effect of a vanishing pseudogap on the magnetic excitations in overdoped ...
One of the major issues in high temperature superconductivity is the nature of the so called pseudogap phase. A related question is whether the pseudogap controls the evolution... -
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... -
Aggregation phenomena inside polymer brushes: lateral structure
We will use off-specular reflectivity to probe the characteristic lateral length-scales in responsive polyelectrolyte brushes grown by surface-initiated ATRP from solid-liquid... -
Understanding of Competing Magnetic Processes in La0.7Sr0.3MnxFe1-xO3 Perovskite
The aim of this experiment is to complete the understanding of the complex nature of the structural and magnetic interactions in the La0.7Sr0.3Mn1-xFexO3 series of materials in... -
Deuteration-induced phase transition in a multiferroic framework material
The hybrid organic-inorganic perovskites are of great interest as functional materials, because they combine the well-established perovskite topology with new physics and... -
Ferroelastic transitions in quantum critical tetragonal tungsten bronzes
Tetragonal tungsten bronzes have three types of channels for ions with the smallest unusually occupied with Li in potassium lithium tantalate (KLT). This creates complexity...
