Crystallographic and Magnetic structures of PrMn7O12
The study of novel manganites, where the tailoring of the Mn formal valence state on the B site is done by the ordering of different cations on the A site of the ABO3 (B:Mn)... -
Neutron diffraction study of crystal structures and magnetism in PbRuO3 perov...
We have synthesised the ill characterised perovskite PbRuO3 at high pressure and temperature. Synchrotron powder x-ray diffraction shows the room temperature structure to be... -
Structural study of oxygen ion conduction in microporous Mayenite
The crystal unit cell of mayenite, 12CaO.7Al2O3, consists of a cubic lattice of [Ca24Al28O64]4+ with the remaining 2*O2- contained in cages, which are linked by channels within... -
Magnetic Properties of Rare-Earth Carbonates
We have prepared a new family of rare-earth carbonates, R4(CO3)6(H2O)2en (R=Dy-Lu). With the exception of R=Er, all materials exhibit a steadily decreasing meff below 70K. The... -
Dynamical disorder or incipient nano-ferroic distortions in CaSnO3 perovskite?
It has always been assumed that CaSnO3 perovskite remains orthorhombic (Pbnm) as a function of temperature up to its melting point, and is rather unremarkable in many ways.... -
The Interaction of Ammonia with Binary and Ternary Deuterides;
The interaction of ammonia with binary hydrides (prototypically, the interaction of LiH with ammonia gas) is thought to be the predominant interaction for hydrogen production... -
Decomposition studies of Li(1-x)NaxND2, LiNa2(ND2)3 and Li3Na(ND2)4
We ask for 3 days on GEM to study in-situ the decomposition of the Na-substituted LiNH2 phases, Li1-xNaxND2, LiNa2(ND2)3, Li3Na(ND2)4 and their reactions with LiD. LiNH2 is the... -
The structure of hydrogen in calcium-ammonia-graphite: an in situ time resolv...
The aim of this proposal is to determine the in-plane and out-of-plane structure of H2 in the two dimensional galleries of stage-I calcium-ammonia-graphite intercalates: this... -

Towards an accurate structural phase diagram for the novel BiScO3-PbTiO3 ferr...
The aim of this experiment is to determine accurately the crystal structures of phases in the (1-x)BiScO3-xPbTiO3 (BST-PT) perovskite phase diagram, particularly in the vicinity... -
High pressure evolution of magnetic state and crystal structure of Pr1-xCaxMn...
Recently insulator-metal transition in Pr0.7Ca0.3MnO3 was observed at P = 0.5 GPa, implying a change in magnetic ground state, which was initially a pseudo-CE AFM one. In later... -
O/N-distribution in host lattices for rare-earth doped phosphors in light emi...
Nitridosilicates and oxonitridosilicates (sions) gain more and more importance as host lattices for rare-earth doped phosphors in light emitting diodes. By means of... -
diffuse scattering in PMN-PT crystals
Complex mixed-ion pervoskites, ferroelectric material (1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3, attract plenty of applications due to high piezoelectric response. The difficulties result... -
Structural studies of bioactive yttrium doped alumino-silicate glasses.
Yttrium doped glasses are of considerable interest due to their potential for use as in-vivo radioactive beta- emitters for localised treatment of liver cancer and other... -
VT studies of the local structure of a fuel cell cathode and lead-free ferroe...
We are about to submit a detailed pair distribution function study of a new lead-free ferroelectric material based on RMC analysis. This method will be applied in VT studies of... -
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... -
Texture memory and variant selection for steel and titanium and zirconium alloys
The proposed experiment will focus on determining the level of texture memory and variant selection on both heating and cooling for steel and titanium and zirconium alloys with... -
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... -
On the inhomogeneous ground state of the two-dimensional frustrated antiferro...
The layered NaMnO2 is challenging as it is an experimental realization of a two-dimensional spin-2, spatially anisotropic triangular lattice, where the interplay of temperature... -
