Copy of: Local magnetic order and the paramagnetic-parmagnetic transition in MnO
The antiferromagnetic-paramagnetic transition in MnO at 118 K occurs at a much lower temperature than anticipated from its Curie-Weiss constant theta~550 K. Consequently, strong... -
In-situ studies of alkaline earth nitride deuterides
Heavy alkaline earth nitride hydrides (AE2NH, with AE = Ca and Ba) are of interest due to their potential suitability as electrolyte materials in a variety of electrochemical... -
Small-angle neutron scattering studies of phase separation in Fe-Cr based alloys

In situ NPD investigation of double perovskite manganites in wet hydrogen atm...
The aim of the experiment is to investigate by means of in situ NPD the structural behavior of two new Mn-rich double perovskites compounds, NdBaCo1.5Mn0.5O5+d and NdBaMn2O5+d... -
Structure-conductivity relationship in La2-xBaxNiO4+d
Unusual total conductivity behaviour at high Ba contents may be attributed to a change in conduction mechanism at high tempertaures, structure change or phase... -
Investigation of the phase transition in La2Mo2O9 from structural and conduct...
There has been significant interest in the oxide ion conducting material La2Mo2O9 as a new electrolyte after initial reports of conductivity as high as that of YSZ at lower... -
Defect structure in W/Ln and Ta/Ln di-substituted bismuth oxide based solid e...
The stability regime of the oxide ion conductor delta-Bi2O3 is limited to a narrow temperature range just below its melting point. Substitution of Bi3+ by a variety of isovalent... -
Local structure in layered perovskite oxides - probing ion transport in fuel ...
Layered oxides are increasingly attractive as electrode materials in energy technology applications, such as fuel cells, electrolysers and permeation membranes. As the... -
Structural and Magnetic Characterisation of New Polar Oxides with Weak Ferrom...
The synthesis of a phase combining electrical polarisation P and spontaneous magnetisation M is hard because of the distinct electronic structure requirements for the main... -
Order-Disorder Transitions in Layered Tellurides
We have prepared a new series of layered tellurides Cr2-xInxGe2Te6, containing 2D ordered arrays of (Cr,In) cations and (Ge-Ge) pairs. Recent neutron measurements reveal indium... -
In-situ QENS studies of the nitridation of Calcium Hydride
The proposed experiment will study how material properties change as a function nitridation (eg. the incorporation of nitrogen gas into the material). In previous study at RAL,... -
Structure and composition of oxide nano-composites for application as SOFC ca...
Solid oxide fuel cells (SOFCs) are devices for converting liquid or gaseous fuels directly to electrical current. They rely on high oxide ion conductivity throughout the device... -
Effect of texture on generation of intergranular stresses in 316H
Intergranular stresses are generated in polycrystalline material due to anisotropic deformation during monotonic and cyclic loading. Such generated intergranular stresses can... -
In-situ conductivity study of double perovskites for use as potential anode m...
It is a challenge to develop materials for use in fuel cell applications. Presently we are preparing new perovskite and double perovskite structured compounds being potential... -
Towards the development of carbonitrides as novel two-stage regenerable reage...
We are examining a number of cobalt-molybdenum carbonitrides as possible catalysts for reactions that produce nitrogen-containing organic molecules. There is good evidence that... -
Fluorophosphate Derivatives of Gypsum and Lithium in Biogenic Manganese Oxides
This proposal seeks neutron diffraction beamtime to study two important systems. We have demonstrated that monofluorophosphate (PO3F) can be substituted into gypsum (CaSO4.2H2O)... -
High resolution neutron powder diffraction studies of the cubic spinels Li2Ni...
We propose to study the structures of Li2NiGe3O8 and Li2ZnGe3O8 using variable temperature high resolution powder neutron diffraction, with the intention of locating the Li... -
In Search of Superionic Conductivity of Mg2+ Cations
The migration of cations with a charge greater than 1 has received very little attention historically, perhaps due to no commercially driven demand for the research as well as... -
Single-Crystal Neutron Diffraction Study on [U(C5Me5)2(H)(mu¿H)]2
To our knowledge, the length of the U¿H single bond has never been accurately measured, at least not in a molecular compound by single-crystal neutron diffraction. We currently...
