Muon Study of Ion-diffusion in a Novel Sodium Battery Material
Lithium (Li) ion batteries is the most common battery technology but lately also sodium (Na) batteries are being considered. One reason is that the Li-reserves are limited and... -
RF-mSR study of high-Ge Si1-xGex alloys
Single crystal, bulk Si1-xGex alloys are available across the alloy composition range, and provide opportunity for study of alloy properties in transition between the two... -
Ionization of Neutral Shallow Donor Muonium in beta-Ga2O3
We propose RF-MuSR experiments focused on confirming the two shallow Mu donor states tentatively observed in single crystalline beta-Ga2O3 samples. This material is a candidate... -
Spin orders in CaxMn2-xFeReO6 double perovskites
New manganese-based double perovskites Mn2-xCaxFeReO6 have been synthesised at high pressure. Mn2FeReO6 has spin-active cations at all sites; S = 5/2 Mn2+, S = 5/2 Fe3+ and S =... -
Magnetic ionic liquid surfactants
This proposal is to explore the magnetic properties and molecular dynamics of a new class of magnetic ionic liquid surfactants1 (MILSs) (see Fig. 1). The MILSs investigated here... -
Is there an incommensurate magnetic resonance in La2-xSrxCuO4?
Most optimally-doped high- Tc cuprate superconductors show a magnetic excitation (known as the 'resonance') at q=(pi,pi ) whose intensity increases sharply below Tc. This... -
Magnetic relaxation processes in tetragonal lanthanide single-molecule magnets
Single-Molecule Magnets (SMMs) are molecules that display slow relaxation of their magnetisation. We have designed a new class of mononuclear lanthanide SMMs, where the... -
Detecting static magnetic order in mutiferroric Lu1-xScxFeO3 through µSR study
Multiferroic systems have been a long-lasting and productive research field of condensed matter physics in both fundamental and applied perspectives. Useful multiferroic systems... -
Diffusive behavior in novel anode material, LixY2Ti2O5S2
This proposal describes a muSR experiment for studying a diffusive nature of Li ions in novel anode material for Li-ion batteries. The target compound, LixY2Ti2O5S2 (LxYTOS,... -
Quantification of the iodine content in a conducting polymer: polythiophene
Polymeric solar cells are a promising alternative for producing clean and renewable energy due to the possibility of fabricating them onto large areas of lightweight, flexible... -
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... -
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... -
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... -
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... -
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... -
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... -
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... -
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... -
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... -
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...
