Are magnetic excitations in the Yb based pyrochlores really gapless?
A recent neutron study of a powder sample attests a splayed ferromagnetic structure for Yb2Ti2O7. However in the same work the authors report gapless magnetic excitations even... -
Surface structures of polycations in confined geometries
A second-generation surface force style apparatus has been developed to probe the inter-surface and near-surface structures under compressive forces. Systems of current academic... -
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,... -
Proton diffusion in lithium imide: a quasi-elastic neutron scattering study
Li_2NH has been recently considered for H_2 storage applications. However, its low-T crystal structure is still controversial, with at least 6 options compatible with the... -
Measurement of Residual Stresses in Side-Punched Single Edge Notched Bend Spe...
Residual stresses have been generated, mechanically, in single edge notched bend specimens by side-punching ahead of sharp notches. Given that this is a novel method of... -
Determination of the diffraction elastic constants of Inconel 718 at high tem...
Within our project we are studying the evolution of stresses in Ni-base superalloy IN718 during annealing heat treatments. This is done by performing in-situ neutron diffraction... -
Field Induced Metamagnetic transition close to Ferromagnetic Quantum Critical...
This proposal addresses the formation of a metamagnetic phase transition in PrPtAl. PrPtAl exhibits induced moment magnetism where singlet-mixing is stabilised by inter-site... -

Inelastic neutron scattering study on the one dimensional spin-chains
One-dimensional (1D) spin chain is interesting to understand the low dimensional magnetism. For a 1D spin chain, long rang magnetic order cannot exists at finite temperature. On... -
Interlayer Dynamics in Graphite Intercalation Compounds
Alkali metals are well-known to form regularly-layered graphite intercalation compounds (GICs) which exhibit a number of novel and practically important structural and... -
Neutron Diffraction residual Stress Measurement in Cold Weld Repair Tubular J...
Grade 91 pipes and tubes have become a standard material for the design of new and refurbishment of existing Power Plants. Several major failures have been encountered after... -
Measuring strains in geologically important hydrous minerals
We request 4 days of beam-time on ENGIN-X to measure the elastic behaviour of polycrystalline samples of gypsum, antigorite, and talc as a function of uniaxial load. All three... -
The mobility of ions in molten nitrates
This proposal is a continuation of a study of molten salts which have a large number of applications, including applications in fuel cells and, in the case of nitrates, as...
