Ordered double perovskites (also known as elpasolites) have the general formula A2BB’O6 where A is generally a rare earth metal or alkaline earth metal and where B and B’ are...

In a typical magnetic material the interactions between neighbouring magnetic moments will tend to lead to their ordered alignment throughout the entire structure as it is...

This proposal is part of our project to investigate the unusual physics of 5d transition metal oxides. In particular, we are studying two samples of the chemical composition...

We have recently carried out an inelastic neutron scattering experiment at LET in order to investigate the excitations in the quantum spin ice Yb2Ti2O7. The single crystal...

Multiferroics of spin origin, for which magnetic long-range order and electric polarization occur simultaneously, have attracted considerable interest. The strong coupling...

The family of hybrid Prussian blue analogues includes many electroactive materials, where organic cations moving within the pores of the cyanide framework cause unusual and...

Molybdenum based-oxides have recently attracted interest for use as electrolyte and electrode materials in Solid Oxide Fuel Cells. This proposal requests 5 days of beamtime on...

Relaxor ferroelectrics are a class of locally disordered crystals possessing peculiar structure and electrical properties. The solid solution of a relaxor perovskite and PbTiO3...

The purpose of this project work is to establish a broader understanding of the magnetic proximity effect observed in a magnetic amorphous multilayer. This will be achieved by...

The research on new anode materials for solid oxide fuel cell is extremely important for its potential to overcome the drawbacks of current state of the art anodes. In this...

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...

The hydroxides Me(OH)2 of the bivalent transition metals Co, Cu, Fe, Mn, Ni, Cd and Zn play critical roles as sorbents, catalysts or reductants in many environmental and...

The Earth¿s climate is strongly influenced by atmospheric aerosols. Organic surfactant films on these aerosols influences their size, optical properties and ability to act as...

Pyrolysis is considered as a sustainable way to generate energy from bio-oil, however, biochar – a solid residue by-product– is inevitably produced in the production line. We...

Although microemulsions have been widely investigated as potential drug delivery vehicles, relatively little work has been performed establishing the detailed molecular...

Lu3Os4Ge13 is an interesting superconducting system, with potentially unconventional physics. It is a low carrier density semi-metal, exhibiting superconductivity at 3.1 K. This...

Alkali-cluster intercalated fullerides (LixC60, NaxC60) proved to be suitable materials for solid state hydrogen storage. In these compounds the hydrogen is chemically absorbed...

We propose to use a pulsed magnet system tried and tested at several neutron and synchrotron facilities in conjunction with the new high flux diffractometer WISH to perform the...

Materials with helical and double helical structure motifs are prone to display fascinating spring-type behaviour, i.e. a shallow energy surface along the spring-axis in which...

Asphaltene, the most polar fraction of petroleum crude oil, is present at concentrations that can vary from virtually zero to 20 % w/w depending on the oil origin. Asphaltene is...
