Structure and cation ordering in A2Sn3Q7-type phases (A=In, Cr; Q= S, Se)
We wish to exploit the contrast afforded by neutrons to study the ordering of In and Sn cations in indium tin chalcogenides. Cation ordering has been inferred from spectroscopic... -

Influence of the cation disorder on the magnetic properties of underdoped cup...
We want to isolate the effects of doping, charge localization and local distortion on the transition from insulating antiferromagnet to superconducting metal in YBCO. We choose... -
Rosseinsky programme access GEM
The proposal develops recent observations on spin-lattice coupling in incommensurate materials (objective - measure influence of applied field on evolution of structural... -
Local structure in cation substituted Zn2TiO4 inverse spinel
Considerable research has been devoted to materials to fulfil the roles of electrodes and electrolyte within SOFCs, with focus on the fluorite or perovskite crystal structures.... -

Spin and cation order in AMn3B4O12 perovskites
A-site-ordered perovskite oxides with formula AA'3B4O12 have a rich variety of physical and chemical properties. Most have Jahn-Teller active Cu2+ or Mn3+ at the square-planar... -

Interlayer and Interparticle Water in Clays
Clay barriers are routinely used in nuclear waste repositories to isolate radionuclides from the biosphere. Such barriers have to be carefully designed to remain effective for... -

To determine the temperature evolution of the structures of two Bi-based perovskites with commensurate structures through their magnetic transition temperatures to contrast... -
Isovalent cation substitution and the AF-SC boundary of oxypnictides
We have prepared a new family of electron-doped oxypnictides \RFeF\ with the same average Rare Earth radius as that yielding the highest superconducting Tc to date, i.e. the... -

Study of cation disorder, oxygen vacancy ordering and proton sites in La2-xNd...
On the basis of X-ray diffraction the oxygen deficient La2-xNdxCe2O7 series displays a transition from disordered fluorite to the C-type superstructure in which the cations... -
