The topotactic reduction and anion exchange of complex oxy-halides
The reaction of LiH with the oxy-chloride Sr3Fe2O5Cl2 initially leads to the topotactic deintercalation of oxide ions and the formation of Sr3Fe2O4Cl2 containing sheets of... -
Monitoring Gamma Prime Evolution in Superalloys using Small Angle Neutron Sca...
The aim of the experiment is to monitor the temporal evolution of gamma prime precipitates in three polycrystalline nickel base superalloys using Sans2D. This instrument is... -
The role of water in homogeneous catalytic processes mediated by water solubl...
A large number of chemicals are currently obtained by catalytic synthetic processes, but usually in most of these processes the catalyst remains in the reaction medium during... -
Solventless protein liquids: a novel form of biological matter
Solventless protein liquids (SPLS) represent a novel form of biological matter. Recently we reported on the preparation and properties of a solvent-free liquid protein based on... -
Magnetic Structure of Candidate Ferroelectric Metal
Perovskite oxides exhibit a large array of interesting electronic properties. Owing to their difficult synthesis (requiring extremely high pressures) the MOsO3 Osmates offer a... -
Resonant Spin Excitation in Single Crystal of Ba0.3K0.7Fe2As2
We recently observed a resonant spin excitation in Ba1-xKxFe2As2 (x=0.4), one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates... -

The present proposal leans on the study of the elastoviscoplastic behavior of a polycrystalline Co by neutron diffraction (ENGIN-X) in line with theoretical investigations : 4... -
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... -
Modification of an adsorbed cationic layer by anionic surfactants below the CMC
In this proposal, we request beamtime to study the unexpected behaviour of a strongly bound bilayer of the cationic surfactant didodecyldimethylammonium bromide on the anionic... -
Spin waves in the single layer half doped manganite Pr0.5Ca1.5MnO4
We propose to measure the spin wave dispersion and intensities throughout the Brillouin zone of the single layer half-doped manganite Pr0.5Ca1.5MnO4, whose ground state has the... -
Investigations on magnetic structure and spin density wave ordering in two di...
Amongst the various layered compounds [Ca2CoO3][CoO2]1.62 (CCO) is very intriguing because of its complex crystal and magnetic structure which is yet hidden. The crystal... -
Structural relaxation in liquid Gallium
Cooling down a liquid at ambient pressure all except Helium attain a solid state. If a crystalline state is reached a dramatic change in long range order occurs manifesting the... -
PNR study on the exchange bias propagation in the FM/AFM/FM trilayer with a t...
Today, a number of technological devices, such as the readout sensor in the hard disc drive, have used the exchange bias (EB) effect, which arises in a... -
Quantifying the volume isotope effect in high-pressure forms of ice
Water ice forms a remarkable diversity of structures, occurring in as many as 17 crystalline forms. Water ice also shows other interesting and unusual properties. For example,... -
Temperature dependence of spin dynamics near quantum criticality in an Ising ...
This proposal is part of our research programme to explore the interplay of thermal and quantum fluctuations near zero-temperature quantum phase transitions. Here we plan to use... -

Finite temperature intraband magnon scattering in the Haldane chain compound ...
The spin-1 antiferromagnetic chain (or Haldane chain) is a model system which was predicted by Duncan Haldane to have gapped magnon excitations due to an underlying topological... -
In situ hydration study of the novel ionic conductor Ba7MoNb4O20
Oxide-ion and proton-conducting materials attract considerable interest thanks to their application as electrolytes in solid-oxide fuel cells (SOFCs). We have recently... -
QENS studies of conductivity/hydride diffusion in barium hydride
BaH2 has application in hydrogen storage technologies. We propose to study BaH2 by Quasi-elastic neutron scattering. We will perform scans at different temperatures for up... -
Ground state magnetic structure of EuCuAs
One of the major themes in solid-state physics is the realisation of exotic types of relativistic electrons which travel at speeds much slower than the speed of light. These...
