Our uSR measurements on superconducting Y1-xErxNi2B2C shows a slowing of the Er spin dynamics upon cooling to 2.5 K, but the depolarisation rate does not critically diverge and...

We wish to measure the high field ALCs of a series of related functionalised acenes, to understand the role of the ligands on the electron spin relaxation, which is of...

We have recently performed high field ALC measurements on the polycrystalline Metal Tris(Hydroxy-quinolate), MQ3, series in order to further investigate the intrinsic electron...

Preliminary measurements of [FeFe]-hydrogenase model complexes were made in a previous experiment using EMU (RB 1010177). The results were interpreted in combination with DFT...

Using muon spin relaxation and ALC resonance spectroscopy the electron spin relaxation and mobility of the polymer P3HS will be measured as a function of temperature. The...

Repolarisation and level crossing resonance will be studied for several different oxalate compounds where muon radical states are known to be formed. Such compounds form a...

In a previous experiment (RB910492) we have made preliminary measurements of the rates of addition of muonium to vitamins C and E, as suggested by the ISIS panel. These rates...

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...

Our muSR study on Ce(Os1-xFex)2Al10 with x=0.4, which reveals long range magnetic ordering below 24K from the heat capacity, shows unexpected behaviour. The muSR spectra only...

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....

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...

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...

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...

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...

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...

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...

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...

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...

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...

This proposal looks to study the electron spin relaxation using high field ALC measurements in two polymers, which differ only by the non-metal (i.e S or Se) in the polymer...
