The structure of ammonia borane in ammonia and THF
In this proposal we aim to understand the solvation of AB by two of the most important solvents ? ammonia and THF. Neutron diffraction is a key technique in this context because... -
Crystal structure of a new hexagonal layered cobaltate LaBaCoO4+y
We have synthesized a new cobalte oxide compound. We know from preliminary measurements that its crystal structure is hexagonal, and that the magnetic behaviour is intriguing.... -
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... -
Local magnetism, magnetic fluctuations and disorder, and lattice distortions ...
We aim at performing temperature (2-300K) and magnetic field (0-5T) dependent muon SR on a 1X1 cm2 mosaic, made of 4* 5x5x2 mm3 TbMn0.98Fe0.02O3 single crystals (largest area... -
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... -
Characterization of local symmetry breaking in superconducting La2-xBaxCuO4 &...
The mechanism of high temperature superconductivity (HTSC) remains unresolved. Of particular interest is the origin of the mysterious pseudogap (PG, a partial gap in the... -
Magnetic properties of graphene
Magnetic properties of graphitic compounds are of current interest for both theoretical and experimental research in the fields of condensed matter physics and magnetism. In the... -
Unusual polymorphism in sodalites
We have recently observed extraordinary polymorphism on cooling various sodalites under vacuum. Materials undergo a phase transition followed by a fully reversible... -
µSR study of mixed intercalated phases NaxLi6-xC60
Alkali-cluster intercalated fullerides (LixC60, NaxC60) proved to be suitable materials for solid state hydrogen storage. In these compounds the hydrogen is chemically absorbed... -
Surveying Hebel-Slichter peaks in conventional-ish superconductors
The presence of a Hebel-Slichter peak in NMR or µSR measurements just below the critical temperature of superconductors is taken to be strong evidence for conventional behaviour... -
Homogeneous nucleation in phosphate-based glassy precursors to fast-ion condu...
The structure of the phosphate materials Na_{1+x}Ge_{2-x}Al_x(PO_4)_3 with x = 0, 0.4 and 0.8 will be investigated using high real-space resolution neutron diffraction. In the... -
Investigation of the magnetic phases of the charge transfer compound CuTCNQ
The charge transfer compound CuTCNQ (TCNQ = 7,7,8,8-Tetracyanoquinodimethane) exhibits switching between two electrical resistance states when subject to an electric field. It...
