Understanding the spin-Peierls Transition in KTCNQ and derivatives
Motivated by work showing that magnetic coupling between TCNQ anions in potassium TCNQ (KTCNQ) can be changed simply by changing the aromatic substituents, we seek to qunatify... -
MuSR study on the duality of itinerant and localized magnetism in UIr
The main purpose of this investigation is to discern the localized and itinerant contributions in the ferromagnertic superconductor UIr.Field dependent MuSR measurments up to... -
Muon probes of hydrogen-bond network in supercooled water
Muon diamagnetic fraction in liquid water is known to decrease with decreasing temperature probably because its formation mechanism results from the structural alternation and... -
The search and optimisation of Delta0 resonances in TIPS-Pentacene in solution
To the best of our knowledge, there is no previous work on using muons to measure photo-excited states in organic semiconductors or related materials. Our photo-excitation ideas... -

To address the safety problems of lithium-ion batteries mainly caused by to flammable liquid electrolytes, all-solid-state-lithium-batteries (ASSLBs) with solid-state... -
High Temperature μSR Study of Green Dioptase: Muon or Proton Diffusion?
Green dioptase is a naturally occurring mineral, that has a deep green colour, similar to that of an emerald, and with a chemical formula of CuSiO3.H2O. The Cu lies in quasi-1D... -
Mechanical disorder-induced quantum spin liquid in a two-dimensional triangul...
The quantum spin liquid (QSL) state is one of the possible outcomes of quantum fluctuations advancing magnetic systems into a disordered phase. After more than 30 years of quest... -
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... -

With increasing demands for high performance/capacity rechargeable batteries the materials science community is currently facing two severe issues. First of all there is from 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... -
Characterization of Li-diffusion in ordered and disordered cathode materials ...
Lithium-excess cathode materials can deliver high capacity and lead to high energy density. Lithium-excess cathode materials are categorized as ordered and disordered on the... -
Auger recombination in low temperature silicon measured by photo-MuSR technique
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... -
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... -

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... -
Molecular diffusion in supercooled liquid water
Following our μSR experiment on liquid water (RB1720491) we propose to measure molecular diffusion coefficient (the sum of the diffusion coefficients of muonium and oxygen... -
Spin Rotation Experiments at a Pulsed Muon Source using Broadband RF Pulses
In this proposal we wish to explore how the RF-MuSR technique might be developed for measurements akin to FT-NMR. Our work will focus on the broadband excitation of paramagnetic...
