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...

The electron donor molecule BEDT-TTF (ET) provides a versatile building block for constructing molecular metals, superconductors, magnets and quantum spin liquids. A common...

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...

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...

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....

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...

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...

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...

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...

The great majority of known muonium defect centres and muonium substituted organic radicals have essentially spin-only magnetism, with few exhibiting any noticeable departure...

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...

In recent years, nanoparticles have been a major source of interest in a wide range of fields. Our long term objectives are tuning the free radical reactivity on the surface of...
