Negative thermal expansion in the rutile phase of ZnF2
It has recently been discovered than the rutile phase of zinc fluoride shows negative thermal expansion along all three crystallographic axes. What is highly unusual about this... -
Radiation induced hydrogen abstraction - A combined X-ray and neutron diffrac...
X-ray induced radiation damage drastically limits the structural information accessible in diffraction experiments from macromolecules at 3rd generation synchrotrons. Relatively... -
Unpicking the signal of partial order from thermal motion in diffuse scatteri...
Orientationally-disordered water molecules in ice adopt a degree of partial order upon cooling, a process that is halted by kinetics at ~100 K in pure ice and ~60 K in KOH-doped... -

X-ray induced radiation damage drastically limits the structural information accessible in diffraction experiments from macromolecules at 3rd generation synchrotrons. Relatively... -
PDF study of the structural disorder in a quantum spin liquid candidate
We have identified a potential quantum spin liquid by tuning the magnetic interactions on a square lattice through d10-d0 cation mixing. MuSR shows dynamic magnetism down to... -
Understanding low temperature Nd ordering and double magnetization reversal i...
We aim to understand magnetization reversal phenomenon, observed in the NdFeO3 perovskite, by deriving the evolution of Nd3+ and Fe3+ moments ordering from neutron diffraction... -
Spin ordering in the iridium oxide pyrochlore A2Ir2O7
Here we propose to search for magnetic order in 3 variants of the A2Ir2O7 (A=Y, Nd, and Lu) system. A fundamentally new, moderately-coupled, electronic ground state has been... -
Competing degenrate magnetic states in Ba1-xNaxFe2As2
Magnetic and superconducting ground states have been proposed to coexist in a relatively narrow compositional range in the so-called 122 pnictide superconductors. We recently... -
Structural evolution in the solid solution Na2-x+yHxTi3O7 studied by neutron ...
Layered Na2Ti3O7 has shown promising electrochemical performance to be used as anode material in room temperature sodium ion batteries. We have synthesized several phases in the... -
Ordered structures in the new Topological Insulators
We propose to investigate the structure of the new ¿ordered¿ phases within the Bi2Se3-Bi2Te3 phase diagram of the newly discovered Topological Insulators. The bulk properties of... -
Low-energy spin dynamics of a quantum analogue of ice
Quantum spin liquids are exotic states of magnetic matter in which conventional magnetic ordering is suppressed. Magnetic analogues of ice are good candidates to observe this... -
Local structure studies by PDF analysis of novel Li-rich double perovskites a...
Recently, our group has prepared a series of new double perovskite materials (Li1.5La1.5MO6, M=W6+, Te6+) which display interesting electrochemical behaviour for use in Li-ion... -

We have elaborated a new nano-crystallized high capacity Li-Mn-O cathode material, exhibiting record reversible capacities larger than 355 mAh/g and good cyclabilities. RT... -
Structural and Magnetic Properties from Charge Orders in Iron Perovskite Oxides
Highly oxidized transition metal cations in oxides tend to display unusual electronic and magnetic behavior due to the highly covalent nature of the M-O interactions. Iron is of... -
X-ray Radiation damage to DNA at the atomic level
The interaction of ionizing radiation such as X-rays with biological samples causes damage to the samples. Recent work from our group with various protein crystals, peptides and... -
Structural characterisation of a pyrochlore solid solution in the Na2O●...
3 days on POLARIS are requested to study three pyrochlore compositions in the Na2O●Bi2O3●TiO2 system that has been reported only once in the literature, without any...
