Electron polarisation in CdS and CdTe
At low temperatures and high magnetic fields, the electron in a muonium or radical state may be polarised if it has an opportunity to reach thermal equilibrium. Such a... -
Quantum State Manipulation in PTFE.
Discrete energy level form in quantum mechanical systems and if carefully measured the population density of the levels can be probed and manipulated. The consequence of this... -
Novel ground states and spin ordering in iridate pyrochlores
We request four days of beam time to conduct zero and longitudinal field measurements on iridate pyrochlores A2Ir2O7 (A = Y, Lu, Nd) in the temperature range 200 K to 2 K and in... -
Investigation of carrier transport in the organic semiconductor 8-hydroxy-qui...
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... -
The structure-magnetism relationship in hydrogen bonded coordination polymers
Gaining control of the building blocks of magnetic materials will enable the design and growth of bespoke magnetic devices. However, the ability to tune the magnetic... -
Molecular Dynamics in Polystyrene
A basic understanding of the dynamic processes in polystyrene (PS) is a question of utmost interest and has technological ramifications due to its importance in commercial... -

BaCu2Ge2O7 is reported to be a one dimensional Heisenberg antiferromagnet, with three dimensional long range order at low temperatures due to small antiferromagnetic... -
Musr study of non-centrosymmetric heavy-fermion compounds: CeTSi3 (T=Pt and P...
In view of the interesting magnetic properties observed in CeTSi3 (T=Pt and Pd) and superconductivity in LaPdSi3 (TSC= 2.6 K), as well as the theoretical interest in... -
muSR in the presence of significant spin-orbit coupling
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 electronic structure and magnetic properties of metal nanoparticles stabi...
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... -
A Study of AuMu^+ Final States by Dia RF Resonance
Small-sized metal nanoparticles (NPs) are of long standing interest to both magnetism and heterogeneous catalysis. Muon studies of Au NPs encapsulated in 'SBA-15' silica are... -
Understanding Li-Diffusion and Resultant Magnetism Within Li Intercalated int...
This study involves attempting to understand the Li atom diffusion within Li-intercalated hexagonal boron nitride. Muons present a significant advantage as they are sensitive to... -
MuSR search for fluctuating loop currents in cuprates
The origin of a mysterious pseudogap region in high-Tc superconductors is a challenging issue. It was proposed that the pseudogap is caused by a circulating-current order... -
Kagome quantum spin liquids - The case of Vesignieite
We aim to explore the groundstate of a new near-perfect S=1/2 kagome antiferromagnetic (KAFM) system using MuSR at the lowest possible temperatures. The title compound is... -
Oxygen deficiency in the quantum spin ice Tb2Ti2O7
Tb2Ti2O7 is one of two compounds identified as potential quantum spin ices. As with other oxide pyrochlores the properties depend sensitively on the oxygen content. Most... -
Magnetic Charge Transport in Spin Ice
We have performed further measurements on Dy2Ti2O7 and confirmed the observation of magnetic charge transport. Given the time constraints of our previous experiment not all... -
Dilution of the Near-Kagome Compound Vesignieite
Vesignieite, Cu3VBa2O8(OH)2, is one of very few materials approximating a kagome spin-1/2 Heisenberg antiferromagnet, a model that is the ideal setting for novel quantum spin...
