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... -
Observation of hydrogen dynamics in hydrogen storage materials by muSR
Hydrogen storage materials with a low working temperature are strongly required for the application of the next generation on-board hydrogen storage system. Among several... -
Systematic Investigation of Magnetically Doped Toplogical Insulators
Topological insulators (TIs) are of inherent interest as they are conducting on the surface whilst insulating on the bulk. We would like to investigate magnetically doped... -
Rapid access for Na battery electrodes
The overall aims of our project is to advance the performance of NIBs in terms of energy and power density by creating a closed-loop approach for materials design,... -
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 search for the muoniated hydroxyl radical, OMu
The elusive OMu radical is believed to be formed by muonium reaction with nitrous oxide but has never been directly observed. It would be invisible to transverse-field muon spin... -
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... -
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... -
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... -
Muon States in Nanostructured Carbonaceous Materials
This experiment proposes the continuation of a study, initiated at J-PARC, on a new type of activated carbon material, with a pore structure and chemistry "tunable" in a manner... -
Local Field fluctuations and Mu Dynamics in Vanadium Dioxide Compounds
This is an in depth study of magnetic fluctuations and local field dynamics leading into the low temperature magnetic phase of Vanadium Oxide compounds (VO2, VO2:W and VO2:Ti)... -
RF MuSR in the gas phase: The Search for a Radical State (RB920227)
The main spectroscopic technique for studying radicals in solids and liquids, ESR, cannot usually be used to study radicals of more than 3-5 atoms in the gas phase due to strong... -
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... -
Organometallic Radicals
Avoided level crossing muon spin resonance (ALC-muSR) is an exceptional tool for determining the structure and probing the dynamics of radicals but there have been only a few... -
Low Temperature Study of the Cluster Glass Phase in Ni(TCNQ)2
Recently there has been an M(TCNQ)2, where M=Mn, Co, Fe and Ni, series synthesised where all samples formed a stochiometric glassy ferromagnetic salt. We have focused on the... -
Using muons to investigate the excitation spectrum in low-dimensional molecul...
We propose to use longitudinal field muon-spin relaxation to investigate the excitation spectrum of the most successful realizations of one- and two-dimensional antiferromagnets... -
Muon spin relaxation studies of KTCNQ and related compounds
Potassium tetracyanoquinodimenthane (KTCNQ) undergoes a spin-Peierls (SP) transition at 396K where a transformation from uniform to dimerised TCNQ- molecules in 1D columns... -
Models of the [FeFe]-hydrogenase active site: raising the symmetry
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... -
Investigating the muon radical in Sulphur
Recent muon level-crossing measurements in the stable orthorhombic alpha-phase of sulphur indicate the existence of a radical state, with an interesting temperature evolution....
