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... -
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... -
Probing adduct radicals in graphite
Graphite has been the first material ever studied by µSR, but a comprehensive scheme to understand its behaviour still lacks. In particular it is not properly known if and how... -
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... -
Low Temperature Properties of a Uniform S=1/2 Triangular Lattice System
It is proposed to use ZF and TF muSR to study the low temperature, low field part of the phase diagram of Ba3CuSb2O9, a system with a uniform triangular lattice of S=1/2 Cu ions... -
The XY pyrochlore AFM:spin dynamics upon rare-earth dilution in Er2Ti2O7 (CON...
Er2Ti2O7 constitutes an experimental realization of the <111> easy-plane pyrochlore AFM and orders at 1.1 K into the theoretically predicted spin structure. However, the... -
Propagation of magnetic excitations on one dimensional spin chains
For one-dimensional quantum spin chain systems recent experimental and theoretical studiesindicate unexpectedly large, in some cases diverging spin and heat transport... -

Developing QLCR spectroscopy as a muSR tool
Quadrupolar level crossing resonance (QLCR) in muSR of solid state systems with diamagnetic muon states in proximity to quadrupolar nuclei was discovered many years ago, however... -
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... -
Continuation: 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. Recent muSR studies of Au NPs encapsulated in mesoporous... -
Muon Investigation of sodium super ionic conductors for sustainable and safe ...
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... -
Determination of the Magnetic Properties of LaFeAs1-xPxO Across Multiple Magn...
LaFeAs1-xPxO has recently been proposed to display unusual properties as a function of P doping with two distinct superconducting (SC) domes separated by a possible AFM phase as... -
Hydrogen impurity in solar cell materials CIGS and CZTS
In this proposal we intend to complete the characterization of the hydrogen impurity in solar cell materials Cu2ZnSnS4 (CZTS) and Cu(In,Ga)Se2 (CIGS), by using the positive... -
Relaxation plateau in the breathing pyrochlore antiferromagnet LiIn0.05Ga0.95...
In physics, frustration describes a situation where a system is unable to satisfy all of its internal interactions because of the geometry of its atomic structure. The most... -
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... -
Muonium in widegap oxides
This proposal is part of a long-range program aiming at determining the stable charge-state configurations, site and impurity energy levels (donor and/or acceptor) of hydrogen... -
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... -
Metal decorated graphene for Hydrogen Storage
Previous uSR measurements on chemically produced graphene showed that, apart from a slowly relaxing graphite-like fraction, approximately 40% of the implanted muons are trapped... -
Studying the Temperature Dependence of The Slower μSR Frequencies in CsN...
We seek to continue our study of CsNiCl3 to determine the nature of the two magnetic transitions.Previous experiments at PSI have shown there are two distinct muons sites, one...
