Spin dynamics in the quantum spin ice state of Yb2Ti2O7
We propose to carry out a muSR study of the spin dynamics in two single crystal samples of Yb2Ti2O7. Both samples are notionally stoichiometric but they have been prepared using... -
To complete a pressure dependence study of topological frustration in Y(Mn0.9...
While Y(Mn1-xAlx)2 (x<0.02) is seen as a system of AF coupled local Mn moments (T<110K), alloys with 0.02 -

Temperature and environment dependence of the isotope effect in muonated radi...
We plan to measure the hyperfine constants for both the muon and the equivalent hydrogen atom in a small muonated radical using time-differential ALC. We will follow this as a... -
Probing the [FeFe]-hydrogenase using muon spectroscopy
During our previous experiment on HiFi (RB1320541) we measured the ALC spectrum of the Fe2(µ-pdt)(CO)4(PMe3)2 model hydrogenase complex over multiple temperatures. The spectra... -
Investigation of the re-entrant spin glass component and the anomalous Hall e...
Fe3Sn2 is a rare example of an itinerant frustrated ferromagnet (Tc = 640K), with a non-collinear spin structure. It shows a large anomalous Hall resistivity in a low field of... -
Slow magnetic fluctuations and superconductivity in CeRhIn5 at ambient pressu...
CeRhIn5 is an antiferromagnetic itinerant magnet which illustrates a temperature and pressure interplay between antiferromagnetism and superconductivity. Recently, it has been... -
Local magnetism, magnetic fluctuations and disorder, and lattice distortions ...
We aim at performing temperature (2-300K) and magnetic field (0-5T) dependent muon SR on a 1X1 cm2 mosaic, made of 4* 5x5x2 mm3 TbMn0.98Fe0.02O3 single crystals (largest area... -
A muon coherent quantum resonance with I > 1/2 nuclei in A15 compounds
The implanted muon can form a quantum-coherent resonant state when sandwiched between two I=1/2 fluorine ions, where I is the nuclear spin. This state has usually only been for... -
Muons for Energy Nanonics
In order to improve the performance of future energy devices, nano-structured materials is one of the most promising routes. LiFePO4 is a commercial battery cathode material... -
Magnetic Charge Transport in Spin Ice
The transport of electrically charged quasiparticles plays a pivotal role in modern technology. In contrast, the transport of magnetic charges has barely been explored... -
Influence of the cation disorder on the magnetic properties of underdoped cup...
We want to isolate the effects of doping, charge localization and local distortion on the transition from insulating antiferromagnet to superconducting metal in YBCO. We choose... -
Magnetism and superconductivity in hyperexpanded fullerides close to the Mott...
The fcc polymorph of the hyperexpanded fulleride Cs3C60 can be driven to a bulk suprconducting state without symmetry change by the application of pressure. Its Tc passes... -
muSR study of a pi-electron S = ½ candidate quantum spin-liquid state in an i...
Molecular solids whose cooperative electronic properties are based purely on pi-electrons from carbon atoms offer a fertile ground in the search for exotic states of matter,... -
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... -
Investigation of spin dynamics across quantum critical point in Co substitute...
Investigation of correlated behaviour in Ce based intermetallics has continued to fascinate researchers. These compounds exhibit novel ground states depending on the strength of... -
Single crystal study of a-RuCl3, a quantum magnet on a honeycomb lattice
a-RuCl3 is a honeycomb lattice system which is thought to be close to a spin liquid state. The layers are weakly coupled and therefore the system is susceptible to stacking... -
Muon spin rotation to determine internal fields in HfNiSn
HfNiSn is a semiconducting material with cubic crystal symmetry, and as such it should not show any anisotropy in electronic transport.However, at low temperatures we observe... -
Silicon nanoparticles in thermoelectric material applications - Solution stat...
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... -
Kinetics of Hydrogen Abstraction by Mu Reactivity with Propane studied by RF ...
Hydrogen abstraction reactions are key steps in free radical mechanisms that dominate the combustion and atmospheric chemistry of the alkane hydrocarbons and, as such, merit...
