In materials with correlated disorder (i.e. not completely random nor completely ordered), new physics and functionalities can occur. Correlated disorder can be treated...

We recently completed an experiment on LARMOR at ISIS that proved that each individual neutron prepared for a Spin Echo Small Angle Neutron Scattering (SESANS) measurement is in...

Magnetic skyrmions are topologically protected spin structures with potential uses in low power devices. Cu2OSeO3 is a cubic material containing both skyrmions and other spin...

Quantum phase transitions are abrupt qualitative changes of a system's groundstate occurring only at exactly zero temperature. Such critical points - although never reachable...

Lubrication of surfaces by modification with polymer films has proven an efficient method of frictional reduction. Bio-inspired bottle-brush copolymers containing a linear block...

URu2Si2 has been examined intensively over the decades for the rich phase diagram including superconductivity, Hidden Order and multiple magnetic phases appearing around the...

We propose to develop and carry out a novel in situ SR/electrochemical technique to identify the mechanism underlying ferromagnetism in palladium bionanoparticles. We...

The f-electron metal Yb2Pt2Pb is best thought of as a one dimensional (1D) quantum spin chain system, despite the fact that the magnetic moments are large and anisotropic with...

Although the surface properties and self-organisation of end-functional polymers in amorphous blends are well understood, the influence of crystallinity has received little...

The aim of the experiment is to study, in low magnetic fields, the very slow spin fluctuation (MHz range) present in the normal phase of La0.8Y0.2LaFe1-xMnxAsO0.89F0.11...

The high-pressure form of solid water, ice III, is the equilibrium phase in contact with liquid water at pressures from about 2.0 - 3.5 kbar. Consequently, its properties are...

This experiment will establish the structural changes that occur in Amorphous Solid Water (ASW) prior to the process of pore collapse or crystallisation. We will study the...

We propose to investigate the high-energy (above 10 meV) excitations using either the MERLIN or MAPS chopper instruments. CaFe2O4 is interesting for several reasons. First, it...

We have been studying the formation of solid polymer-surfactant films formed from cationic surfactants with PEI. We wish to use the highly organised mesostructures formed in the...

With the discovery of almost 3000 exo-planets it is clear that planet formation is a by-product of star formation, yet in the micron ? cm size range, where relative velocities...

The recent discovery of skyrmions and skyrmion lattices in materials with no inversion symmetry and their corresponding potential applications of Skyrmions in magnetic...

The Sr3CuPtxxIr1-xO6 system has been considered to be a candidate random quantum spin chain. (RQS). For x=1 adjacent S=1/2 Cu2+ions are antiferromagnetically (AF) coupled to...

YbNiSn is an Ising ferromagnet with non-colinear spins that undergoes a first order magnetic transition in low magnetic field (0.9 T). The transition is associated with strong...

The yeast Candida glabrata is becoming an increasing cause of infections. We have developed RNA interference tools that allow us to study the virulence and resistance mechanisms...

In this proposal we wish to explore how the RF-uSR technique might be developed for measurements akin to FT-NMR. Our work will focus on the broadband excitation of paramagnetic...
