S=0.5 kagome antiferromagnets (KAFM) provide the most promising model system for realising the Resonating Valence Bond (RVB) state. Several S=0.5 KAFM materials are currently...

The proposed experiment is to observe optical spin-injection in Silicon through MuSR detection. An important part of research in next generation electronics focusses on the...

Uniaxial stress has been used to study the Fe-based superconductors with spectacular results. Both the transport properties and the low-energy magnetic excitations have been...

This experiment aims to map out the structural phase diagram of the new multiferroic compound hexagonal-YbFeO3 as a function of temperature, both above and below room...

The interplay between electron correlation and spin-orbit coupling gives rise to a variety of exotic electronic states in 5d transition-metal oxides like iridates. One example...

Serine monohydrate undergoes a phase transition at 5.2 GPa which involves reorientation of water molecules. It appears that this disrupts H-bonding elsewhere in the crystal,...

Our neutron study using MARI/MERLIN on Ce(Ru1-xFex) 2Al10 reveals very interesting magnetic excitations and a manuscript is ready to submit to PRB. In x=0 (TN=27 K) a...

Microwave (MW) assisted chemical reactions are of interest as a green, energy efficient alternative to conventional thermal heating for chemical processes. MW irradiation...

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...

An uncommon oxygen absorption/desorption behavior for cobalt oxide YBaCo4O7+d was found[Karppinen et al. Chem Mater 18 2006 490]. Y114 absorbs and desorbs oxygen up to d = 1.5...

We propose to use POLARIS to obtain detailed structural information on a series of new lithium-containing layered oxychalcogenides and to investigate the ordering of lithium...

This proposal was submitted on MERLIN (RB1010206) and beam time was allocated on MARI. We have carried out low energy measurements on MARI and found a clear evidence of the spin...

Organic-inorganic perovskites have recently been shown to be potentially efficient and inexpensive photovoltaics. These materials undergo a series of structural transitions and...

In recent years there has been a large interest in geometrically frustrated magnetic systems, especially those with spins interacting on two-dimensional triangular lattices...

Lithium sulfur (Li/S) batteries have a fivefold higher theoretical gravimetric energy density (2680 Wh/kgsulfur) than state-of-the-art lithium ion batteries. In addition, the...

The proposal addresses the average structures of new lead-free ferroelectrics, low-temperature ionic conductors and mixed conductors which are candidate solid oxide fuel cell...

It is estimated that > 40% of new drug molecules are poorly water soluble. For many reasons, solubilisation in nonionic surfactant micelles is a favoured means of increasing...

The modified pyrochlores AM2+M3+F6 (A alkali metal ion, M transition metal ion) are a class of highly frustrated materials that have a randomness associated with the positions...

Our first completed photo-musr experiment on 6,13-bis(tri-iso propylsilylethynyl) pentacene (TIPS-Pn) has recently been accepted for publication. We observed a significant...

The crystal and magnetic structures of two substituted variants of the multiferroic phase BiFeO3 will be studied as a function of pressure. Both Bi0.8La0.2FeO3 and...
