Main group metal iodometallate represent a large class of semiconducting materials which display optical and electronic properties of current great interest in relation to the... -
Strain effect on the magnetic ground state of the ferroelectric Ca3CoMnO6 system
The search for new ferroelectric materials, where the ferroelectricity results from magnetic frustration, has been a topic of great interest to the condensed matter physics... -
Unravelling the mechanisms of negative thermal in γ-Mg(11BD4)2
We request 2 days on HRPD to perform a detailed study of the low temperature behaviour of γ-Mg(11BD4)2 in order to measure the change lattice parameter as a function of... -
Phase behaviour in double substituted lanthanum manganate MIECs
Bismuth and iron/nickel substitution in lanthanum manganese oxide yields materials showing mixed ionic-electronic conductivity and are being investigated as cathode materials... -
Proving the successful manufacturing of chemically-ordered L10 FeNi
The tetragonal chemically-ordered L10 FeNi phase has recently attracted significant attention for advanced permanent magnet applications due to its compelling magnetic... -
Structural Studies of PbZr1-xTixO3: completing the puzzle in the tetragonal a...
We request 6 days of HRPD time in order to study the structures on the tetragonal side of the lead zirconate-titanate (PZT) phase diagram, a region that has so far been rather... -
The structures of simple halogen bridged complexes
We propose a high-resolution neutron powder diffraction study of the complexes 1, 4-dioxane X2, where X = Cl, Br, I. These are the simplest halogen-bonded complexes in which a... -
Understanding Chemical Expansion in Perovskite Oxides: Impact of Long-Range D...
"Chemical expansion" occurs when some ceramics expand upon releasing oxygen. Their ability to effectively "breathe" oxygen makes them of use in sustainable energy... -
Investigation of the Li-intercalation mechanism for the perovskite Li0.18Sr0....
Our work on LSTN showed that it exhibits favourable electrochemical properties, i.e. rapid diffusion of lithium into the structure at low temperatures and the ability to... -
High resolution neutron diffraction studies of lanthanide zirconolites
The aim of this experiment is to determine high quality structural models for pyrochlore and zirconolite phases in the Y2Ti2-2xFexNbxO7 and Y2-xCexTi2-xFexO7 solid solutions,... -
A high-temperature neutron powder determination of the phase transition and c...
Cu2ZnSnS4 (CZTS) is a solar cell material of great interest. However the material when fabricated, although of high symmetry, contains substantial defect concentration and a... -
Cooperative Jahn-Teller distortions in Ru4+ double perovskites
The aim of the proposed experiment is to use HRPD to follow the temperature dependence of the crystal structures of the double perovskites La2MgRuO6 and La2CoRuO6. This is of... -
Environmental Apatites
Materials adopting the apatite structure are gaining an increasing importance as potential solid-oxide fuel cell electrolytes and for the chemical stabilisation of high level... -
Incommensurate-commensurate phase transitions in K2SeO4
Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such... -
Overcoming Chemical Reaction Equilibrium: Determining the Chemical Potential ...
We have developed and demonstrated a novel process to overcome chemical reaction equilibrium constraints on an important reversible industrial chemical reaction by using... -
In search of origin of metal-insulator transition in honeycomb structure Li2RuO3
Recently we have carried out inelastic neutron scattering measurements on Li2RuO3 to understand the nature of the phase transition at 550K. We have seen a clear inelastic...
