Proposal to determine the origin of the effects of electric fields on the muo...
In the previous proposal we examined the ALC response of components of the complex dielectric under externally applied electric fields (EEF). We saw a shift in the asymmetry at... -
Negative muon spin rotation and relaxation for MgB2 at low temperatures
This is a continuation negative-muon spin rotation and relaxation (mu-SR) experiment on MgB2 having a superconducting transition at 39 K. Since positive muons start to diffuse... -
Local Structure of Bi6WO12 and Bi28Re2O49 Oxide Ion Conductors: Role of Varia...
Oxide ion conductors are technologically important materials with applications in solid oxide fuel cells, oxygen sensors /pumps and membranes for oxygen separation. Two types of... -

Investigating Lead Halide Perovskite Solar cells
Lead Halide perovskite solar cells are the next generation of solar cells, likely to over take silicon and organic solar cells in applications within the next 5-10 years. Lead... -
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... -
Motion of Positevely Charged Muonium Centres in Transparent Conducting Oxides
A continued study of muonium diffusion in transparent conducting oxides (TCO) are proposed. We have ZF depolarization measurements conducted up to room temperatures for SnO2 and... -
Frustration, quantum spin ices and quantum diffusion
This proposal aims to characterise the spin dynamics of three Pr-based pyrochlores that may be realisations of quantum spin ice materials. The lower moment and larger wave... -
Possibility of anomalous magnetic order under zero field in S=1/2 competing s...
S=1/2 quasi-one-dimensional competing spin chain Cs2Cu2Mo3O12 has two dominant exchange interactions of the nearest-neighboring ferromagnetic J1 and the second... -
Investigation of Magnetic Ground State of Hexagonal Rare-Earth Ferrites by µSR
This experiment is focused on exploring and harnessing magnetic ground state of the multiferroic materials, with particular emphasis on the hexagonal (h), rare-earth ferrites... -
Debasement of Roman Silver coinage
The quality of ancient silver coinage is often seen as a comment on the fiscal health of the issuing states. This is nowhere more apparent than with Roman coinages, which... -
Silicon nanoparticles in thermoelectric material applications
In order to meet the UK's commitment to reduce 80% of greenhouse gas emissions by 2050, it is necessary make major advances in efficient, clean and secure energy conversion and... -
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... -
Effect of doping and disorder on the skyrmion phase dynamics in Zn-doped Cu2O...
Skyrmions are topologically protected, nano-sized objects which have been shown to exist in the spin textures of a range of magnetic materials. As we have recently demonstrated... -
Observation of hydrogen diffusion in hydrogen storage materials with muSR
This is a continuation proposal describing an "in situ" muSR experiment on hydrogen storage materials. For the two previous beam-time allocated for RB1510262 and RB1520259, we... -
Probing lithium diffusion in olivine materials LiMPO4 using muSR
We can trace the history of electrochemical cells just over two hundred years back to Luigi Galvani and Alessandro Volta¿s inventions, and perhaps more than a millennium further... -
Investigation of magnetic defects in exfoliated and ball-milled graphite
The recent interest in carbon-based materials like graphene stimulated a deeper analysis of the magnetism in graphite defects. In a previous µSR experiment we observed an... -
High-Energy dynamics and search for a continuum in CaFe2O4
We propose to investigate the high-energy (above 10 meV) excitations using either the MERLIN or MAPS chopper instruments. CaFe2O4 is interesting for several reasons. First, it...
