Magnetic field switching of electric polarisation in Y-type Hexaferrites
The magnetoelectric Y-type hexaferrites demonstrate coupling between magnetism and electric polarisation in relatively small applied magnetic fields, and are hence candidate... -
Chasing the symmetry of the BiFeO3 γ-phase in the isostructural A- and B...
BiFeO3 is by far the most widely studied multiferroic material and yet many mysteries remain in the phase diagram. One mystery is the crystal structure of the high T gamma... -
Temperature induced structural phase transitions in BaPrO3 and acceptor doped...
The sequence of structural phase transitions that occur in distorted ABO3 perovskites as a function of temperature is of intrinsic interest for better understanding of the... -
The magnetic structure of LaMn7O12
Research into the quadruple perovskite manganites has expanded, owing to recent discoveries of technologically relevant properties and entirely novel electronic states. Through... -
Total Scattering Study of Hexagonal and Rhombohedral Bi2O3 Based Electrolytes
Bismuth oxide based electrolytes have been widely studied due to their high oxide ion conductivity. The d-phase of Bi2O3 shows the highest known oxide-ion conductivity of any... -
In situ hydration study of the novel ionic conductor Ba7MoNb4O20
Oxide-ion and proton-conducting materials attract considerable interest thanks to their application as electrolytes in solid-oxide fuel cells (SOFCs). We have recently... -
Determination of the structure of SiO2-rich aqueous fluids at high temperatur...
Many geological processes are governed by the migration of hot, mineral-rich water. These "hydrothermal" fluids are stable at high pressures and temperatures and are important... -
Monitoring Gamma Prime Evolution in Superalloys using Small Angle Neutron Sca...
The aim of the experiment is to monitor the temporal evolution of gamma prime precipitates in three polycrystalline nickel base superalloys using Sans2D. This instrument is... -
Dynamics of Solid Ionic Conductors: Na2Si2O5 and Li2Si2O5
We would measure vibrational spectra for Li2Si2O5 and Na2Si2O5, as well as quasielastic neutron scattering (QENS) spectra for Na2SiO5. The measurement of phonon spectra in the... -
Investigation of pseudo-condensation of supercritical H2 in nanoporous hydrog...
This proposal aims to use small angle neutron scattering for characterization of hydrogen adsorption (including the provision of a quantitative value for the absolute hydrogen... -
The magnetic structures of RMn7O12 (R = Nd, Sm, Dy, Y)
Materials with the perovskite crystal structure are ubiquitous in condensed matter physics. Despite being known for several years, the quadruple perovskites, which afford... -
Phase transitions in non-centrosymmetric Dion-Jacobson Phases
Ferroelectric materials - those which exhibit a spontaneous and switchable electrical polarization - have a wide range of applications. However materials which exhibit... -

Decomposition studies of Li(1-x)NaxND2, LiNa2(ND2)3 and Li3Na(ND2)4
We ask for 3 days on GEM to study in-situ the decomposition of the Na-substituted LiNH2 phases, Li1-xNaxND2, LiNa2(ND2)3, Li3Na(ND2)4 and their reactions with LiD. LiNH2 is the... -
Understanding Chemical Expansion in Perovskite Oxides: Impact of Long-Range D...
"Chemical expansion" occurs when some ceramics expand upon releasing oxygen. Their ability to effectively "breathe" oxygen makes them of use in sustainable energy... -
Structral characterisation of a novel lead free perovskite layer structure an...
Lead free antiferroelectric materials are the focus of much attention for the replacement of lead based materials in electronic devices, such as high energy storage capacitors,... -

To determine the temperature evolution of the structures of two Bi-based perovskites with commensurate structures through their magnetic transition temperatures to contrast... -
Impact of Jahn-Teller Distortions in Sr0.5Pr0.5MnO3
We propose to use the HRPD to establish the sequence of structures, and the nature of the transitions between these, in two complex manganites Sr0.5Pr0.5MnO3 and...
