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)...

U2Pt2Sn crystallizes in the tetragonal Zr3Al2-type structure (P42/mnm, Z = 4), where uranium atoms occupy two different sites. Our measurements of bulk properties have shown...

A 19-electron organometallic radical was produced by the reaction of muonium with ferrocene and characterized by avoided level crossing muon spin resonance (ALC-muSR) and...

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...

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 MuSES project currently ongoing in the HiFi spectrometer gives unique opportunity in the field of photochemistry and photophysics of organic molecules. After two successful...

Following our investigation of alpha-orthorhombic sulphur, we will measure level crossing spectra of some other allotropes and phases, to find if the muon radical observed in...

Spin based electronics (spintronics) is one of the most exciting and challenging areas in nanotechnology. It is expected to be of major scientific and social impact. Very little...

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...

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...

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...

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...

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...

Previous work on the polymer RR-P3HT has found that the ALC resonance collapses at 100K to ~80% of the 300K ALC magnitude, this is much larger than the decrease seen for small...

Dy2Ti2O7 is a pyrochlore antiferromagnet that has a partial magnetization plateau between 0.1 and 0.9T for magnetic fields applied along the [111] direction. This represents a...

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...

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...

Using muon spin relaxation and ALC resonance spectroscopy, the electron spin relaxation and mobility of the polymer P3OT will be determined. P3OT differs in structure to P3HT...

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 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...
