Determining the magnetic structures of NaxCa1-xMn7O12 (x=0.25 and x=0.75): Ca...
Several members of the AA'3Mn4O12 quadruple perovskite family have now been realised, and are known to support intricate charge, orbital, and magnetic ordering phenomena. In... -
Spin, charge and orbital ordering in the new LiMn7O12 perovskite
ABO3 perovskite oxides with Mn on A and B sites are of fundamental interest due tophenomena that emerge from the coupling of charge, orbital and spin orders. Wehave synthesized... -
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... -
Magnetic Structure of Low Temperature Phase of UAu2
UAu2 has an exceedingly simple crystalline structure comprised of columns of U arranged in a triangular lattice, raising the prospect of magnetic frustration. There is a clear... -
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... -
Li(MeNH2)4: Poor Metal, Worse Metal, and Magnet
We request 2 days on GEM to determine the structure of crystalline Li(MeNH2)4: we will be preparing the fully deuterated analogue. Our investigations into the magnetic state of... -
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... -
Magnetic Ordering in a Kagome-like Cobalt Sulphate
We have recently prepared a new cobalt sulphate, Co3(SO4)3(OH)2[enH2], under solvothermal conditions. The structure of this material consists of edge-sharing CoO6 octahedra that... -
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... -

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... -
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... -
A series of robust metal-organic frameworks with exceptional capability for h...
We seek to develop new stable MOFs for practical gas separation and request 3 days on WISH to study the preferred binding sites of adsorbed gas molecules (CD4, C2D4 and C2D2)... -
Magnetic structures of antiferromagnetic heavy fermion CeAuAl3 and CeCuAl3 co...
CeAuAl3 and CeCuAl3 compounds crystallize in the tetragonal I4mm, BaNiSn3-type and display interesting bulk properties. Here we propose to investigate the magnetic structures of... -
