Understanding the spin-Peierls Transition in KTCNQ and derivatives
Motivated by work showing that magnetic coupling between TCNQ anions in potassium TCNQ (KTCNQ) can be changed simply by changing the aromatic substituents, we seek to qunatify... -
Unconventional superconductivity in quasi-1D K_2Cr_3As_3 (QLCR)
Metallic systems with one-dimensional chain-like atomic structure can support unusual mechanisms for electron pairing leading to superconductivity. K_2Cr_3As_3 is one of a... -
Quantum tunnelling of muonium via radical states in molecular solids
The extreme quantum nature of muons and muonium in condensed matter is the result of having a mass that is nine times lighter than that of a hydrogen atom. While this quantum... -
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... -
A GENERAL METHOD OF MEASURING ANTIOXIDANT CAPACITY
Antioxidants are very important molecules because they can prevent or slow down the oxidative damage to our bodies. When our bodies use oxygen, free radicals are released which... -

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... -
Anomalous temperature dependence of the ALC spectrum of polybutadiene
The relative importance of factors affecting the low temperature ALC spectra of organic molecular systems such as polymers and small molecules is a topical issue. Polybutadiene... -
Study of electron spin relaxation in the anthradithiophene series, substitute...
The emerging field of organic spintronics is especially promising for new technologies, owing to the long spin coherence times, large flexibility and low production costs of the... -
Muonium and Flourine Entangled States In An Organic Based Spin Peierls System
Potassium TCNQ is an stoichiometric organic based salt that undergoes a spin Peierls (SP) transition at approximately 390 K. Much research has been conducted on this system in... -
Models of the [FeFe]-hydrogenase active site: high symmetry in a biologically...
The [FeFe]-hydrogenase enzymes are some of the best catalysts know for generating hydrogen. We have an ongoing programme to understand how their chemistry works, and to... -
Commissioning Proposal ¿ Gas Cell Development
An important element of the work associated with the current Framework Programme 7 Joint Research Activity (JRA) for muons is the development of gas sample pressure cells... -
Does Deuteration Change More then the Phonon Spectrum?
Our recent express measurments on protonated and deuterated 7,7,8,8-tetracyanoquinodimethane (TCNQ) have highlighted some interesting differences between the two. We seek to... -
Study of the dependence of electron spin relaxation on molecule length in acenes
We wish to measure the ALCs of a series of polyacene molecules made of a different number of rings. We would like to identify the dependence of the electron spin relaxation rate... -
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... -
Identifying the mechanism behind spin relaxation in organic materials
We wish to measure the low-field ALCs of a series of related functionalised acenes to identify which mechanism (spin orbit or hyperfine) is responsible for spin relaxation in... -

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... -
Multiferroicity in metal-formate perovskites
Recent work has revealed that metal-organic frameworks (MOFs) can also exhibit this multiferroicity. These materials are particularly interesting since their structures are... -
Spin-lattice relaxation in holmium-based high symmetry single-molecule magnets
The study of spin-lattice relaxation in mononuclear lanthanide complexes is justified by the potential applications of these so-called single-molecule magnets in quantum...
