The spin relaxation rates of free radicals in solution can provide valuable information about the dynamics of molecular tumbling in solution, and solvent-radical interactions....

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...

Amorphous molecular magnetic materials Ni2(OA) (OA:organic acceptor) were reported to exhibit ferromagnetism with Curie temperatures >400K. This work is controversial as it...

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

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...

Using the Emu spectrometer at ISIS we have recently studied charge carrier transport in the technologically important molecule 8-hydroxy-quinoline aluminium, by probing the...

We measure electron-hole recombination rate in low-temperature pure silicon using the photo-MuSR technique. The previous works have measured the recombination rate down to -30...

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 measure electron-hole recombination rate in low-temperature pure silicon using the photo-MuSR technique. The previous works have measured the recombination rate down to -30...

In physics, frustration describes a situation where a system is unable to satisfy all of its internal interactions because of the geometry of its atomic structure. The most...

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...

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...

This proposal is part of a long-range program aiming at determining the stable charge-state configurations, site and impurity energy levels (donor and/or acceptor) of hydrogen...

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...

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 have recently synthesised the novel iridocuprate IrSr2Sm1.15Ce0.85Cu2O10. This material exhibits a complex temperature dependence of the magnetic susceptibility with multiple...

Frustrated compounds belonging to the pyrochlore family have attracted significant interest as they can host a huge variety of exotic phases. In order to explore the rich phase...

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...

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...

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...
