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... -
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... -
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... -
Electric field dependence of the crossover from band to thermally assisted tr...
Organic semiconductors have been of major interest in recent years. Amplified by the transition from fundamental physics to new commercial products and technologies, this new... -
Using QLCR to Study Stopping Sites in Molecular Solids
Muon nuclear quadrupolar level crossing resonance is not a well-known technique, however it is extremely powerful. There is a large interest in probing the muon stopping site... -
Electron polarisation of deep muonium states
Following recent experiments in which the shallow donor muon states in semiconductors are found to have significant electron polarisation at low temperatures and high fields, we... -
Development of Radio Frequency µSR as a Method for Determining Hyperfine Coup...
Radio Frequency µSR provides a direct method for accurately determining muon hyperfine coupling constants, Aµ, for muoniated radical species. The method complements the well... -
RF MuSR in the gas phase: The Search for a Radical State
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... -
Searching for the weak ferromagnetism in cobalt and manganese doped TiO2
Diluted magnetic semiconductors offer the possibility of adding the spin degree of freedom to the electrical and optical semiconducting devices that underpin modern technology.... -
RF-muSR in the gas phase: the muoniated ethyl radical
Radio-frequency muon spin resonance is an exceptional technique for studying free radicals, but it has not been applied to study radicals in the gas phase. In a previous... -
Probing the products of free radical reactions in ionic liquids
Many room temperature ionic liquids (salts with melting points near room temperature that hereafter will be referred to as ionic liquids) are ¿green solvents¿ for chemical... -
Muon Studies of Na-ion Diffusion in Novel Low-temperature Cathode Material: "...
The most important scientific problem to solve for our modern society is how to convert and store clean energy. We are currently on the verge for a general breakthrough in... -
Characterizing Mu in 6H-SiC with RF-MuSR
We propose a set of RF measurements on Silicon Carbide (polytype 6H) to identify and characterize the muonium species present below room temperature. One of the main goals of... -
Ion dynamics in Potassium Ordered & Disordered KxCoO2
We have recently presented a novel method to study ion-dynamics in solids using muSR via the hopping rate (nu). We have previously and successfully applied this method to study... -
Searching for magnetic ordering in the S=1/2 quasi-one-dimensional chain magn...
Muon spin relaxation is a remarkably powerful tool for discovering magnetic order in quasi-one-dimensional magnetic chain compounds, particularly when the weak interchain...
