Frustration, quantum spin ices and quantum diffusion
This proposal aims to characterise the spin dynamics of three Pr-based pyrochlores that may be realisations of quantum spin ice materials. The lower moment and larger wave... -
DYNAMICS OF SURFACTANTS IN LUBRICATING OILS
In a recent series of successful experiments at PSI and ISIS we were able to demonstrate the possibility of measuring the rate of transfer of a small molecule (allyl alcohol)... -
Spin relaxation of short-lived spin-labelled radicals in solution
The spin relaxation rates of free radicals in solution can provide valuable information about the dynamics of molecular tumbling in solution, and solvent-radical interactions.... -
Identification and dynamics of muon states in octabutoxy-phthalocyanine
The current experiment proposes to identify and study the spin dynamics of the muon states formed in octabutoxy-phthalocyanine (oBu-H2Pc) using the avoided level crossing... -
Muonium in alpha-boron
Previous muon experiments have identified a muonium state in the commonly occuring, but complex, beta rhombohedral form of elemental boron. To complement recent theoretical work... -
Short-range magnetic correlations in Er(Ni,Cu)Al
The intermetallic alloys RNiAl and RCuAl have been of high interest for several years. They crystallize in the hexagonal structure (ZrNiAl-type) and form various and complicated... -
End-Game: Cornering Solvent Effects on H-Addition in Green Tea Anti-Oxidants
Our ongoing project to characterise radical scavenging by the green tea anti-oxidant EGCG and its D-ring analogue, (3,4,5-(OH)3-Bz) is near-complete. ALC-MuSR experiments on the... -
Auger recombination in low temperature silicon measured by photo-MuSR technique
We measure electron-hole recombination rate in low-temperature pure silicon using the photo-MuSR technique. The previous works have measured the recombination rate down to -30... -

We propose to characterise selected radical structures of the green-tea anti-oxidant flavenoid EGCG (& selected analogues), by DFT/post-HF computation and ALC-MuSR, towards... -
Two Gap Superconductivity of ZrB12
ZrB12 is a cluster boride compound which is superconducting at 6K although the source of the pairing interaction appears to come from the Zr ions with the boron acting as a... -
Utilising Quadrupolar Level Crossing Resonance to Gain Important Information ...
There is much debate about muon stopping sites within materials and in many cases knowing where the muon stops is crucial to understanding the physical properties of different... -
SR study near the ferromagnetic quantum critical point in CePd1-xRhx ...
Rcently the NFL behaviour near an antiferromagnetic quantum critical point (AFQCP) has been investigated extensively. Very recently, we have investigated, for the first time,... -
Order and dynamics in S=1 Ni-based molecular magnets
Recent progress in the field of molecular magnetism has shown the clear potential for gaining control over the structural building blocks of molecular materials in order to... -
Development of Radio Frequency µSR as a Method for Determining Hyperfine Coup...
Radio Frequency µSR provides a direct method for accurately determining muon hyperfine coupling constants, Aµ, for muoniated radical species. The method complements the well... -
Probing the [FeFe]-hydrogenase subsite using muon spectroscopy
Solid state repolarisation measurements of [Fe2(µ-pdt)(CO)4(PMe3)2] (RB 1010177) showed a weak recovery at ca.15G, a strong recovery at ca.100G and what was thought to be a weak... -
Charge transport studies in n-type phthalocyanines (RB920501)
This experiment addresses the study of electron transport in zinc-hexadecafluoro-phthalocyanine (F16-ZnPc), a model n-type phthalocyanine employed in organic electronics, using... -
Muon level-crossing resonances as a probe for studying antiferromagnets at pu...
We propose a set of measurements using the HiFi spectrometer in which muon level-crossing resonances are used to probe the internal field inside antiferromagnets in which the... -
Muon Spectroscopy and Artificial Hydrogenases (RB920382)
The reversible interconversion of protons and dihydrogen is an electrochemical process of fundamental importance to a hydrogen economy. The process requires catalysis to proceed... -
A second generation 2D antiferromagnet investigated with muons
Low-dimensional quantum magnetism continues to be of great theoretical and experimental interest, as reduced dimensionality supports strong quantum fluctuations which can result... -
Variable temperature study of frustrated magetism in Lu2Mo2O5N2
Geometrically frustrated S= 1/2 magnets are of great interest as they do not show classical long range magnetic order at low temperatures and can adopt exotic quantum spin...
