Internal stresses in superconducting bulk magnets studied by in situ neutron ...
Bulk high temperature superconductors are useful for permanent magnet applications because they can generate much stronger magnetic fields than ferromagnets and are more compact... -
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... -
Crystal structure analysis for the new metal-organic framework as a hydrogen ...
New metal organic framework (MOF); C12H12CuN2O4 as a hydrogen storage material has found, and it absorb 2.6 wt% hydrogen at 70 bar. Surprisingly, the absorption curve is still... -
The magnetic structure of an A- site and B-site ordered perovskite: CaCu3Fe2O...
Recently, double perovskites have attracted enormous attention. Now, we have successfully synthesized a quadruple perovskite compound which shows not only one but, both, A-site... -
Structure and magnetic order in chemically modified schafarzikites
Schafarzikite minerals are structurally interesting in having 1-D chains of edge-linked transition metal octahedra. This experiment aims to determine the cause of the... -
Order and disorder in (Mn,Fe)2(P,Si) magnetocaloric compounds
In the high-performance and low-cost (Mn,Fe)2(P,Si) magnetocaloric compounds, the detrimental hysteresis has been significantly reduced by balancing Mn:Fe and P:Si ratios, which... -
Subtle magnetic phase transitions in multiferroic BiFeO3
This experiment seeks to probe the magnetic structure of multiferroic BiFeO3 and its evolution on lowering temperature, with the specific aim of identifying magneto-structural... -
EBSD, DIC and Neutron Diffraction to characterise phase transformation and pl...
Martensitic transformations are solid-state transformations on completion of which a hard phase having very high dislocation density is obtained. Despite often being an... -
Dynamical Transitions in the Ogg Glasses
We request 4 days on IRIS to study the temperature dependance of the structural dynamics in amorphous sodium-ammonia (Na-NH3). This will be the first investigation of the... -
Principal Component Analysis of Phase Behaviour on the Upgraded TOSCA
Principal Component Analysis (PCA) is a powerful chemometric tool for the analysis of multivariate datasets. Capitalising from the recent upgrade of the TOSCA spectrometer, we... -
Structural studies and decomposition of nanostructured ammonia borane-polymer...
Ammonia borane (AB) is a promising hydrogen storage material with up to 12 wt% obtainable from 100 to 150 C. Desorption temperatures can be lowered towards targets and kinetics... -
Magnetostriction in (Bi, La)-orthoferrites
We have recently observed unusual magnetostrictive behaviour in Bi0.5La0.5FeO3 (BLFO), a phenomenon which is not present in either solid solution end member. This proposal seeks... -
Spin excitations in the superconducting FeTe0.6Se0.4
The FeTe1-xSex series exhibits superconductivity over a broad range of doping. Previously we have made extensive neutron scattering measurements on superconducting x = 0.49 and... -
Magnetic structure of the 1D spin chain system: Sr3NiRhO6
The spin-chain systems with general formula A¿3ABO6, crystallizing in the K4CdCl6 (space group R -3 c) type structure has started attracting a lot attention in recent years due... -
Deformation behaviour of gamma double prime strengthened nickel-based superal...
Inconel 718 alloys are widely used in industry. However, deformation behaviour of the different phases in the alloys during plastic deformation under loading has not been... -
Further studies of the Mg(BH_{4} )_{2} and parahydrogen
We found evidence of solid para-hydrogen absorbed in Mg(BH_{4} ){2} up to temperatures of 195 K. Para hydrogen was dosed in Mg(BH{4} )_{2} at 50 K. A series of dosings were... -
Structural and Magnetic Characterizations of the New, High Pressure Synthesiz...
After an almost forty year lull in research on multiferroic materials, there has been a resurgence of interest in them. However, it is particularly challenging to synthesize a...
