This proposal describes an in situ muSR experiment on a hydrogen storage material, MgH2. This is because MgH2 attracts a special attention due to the fact that the hydrogen...

Ammonia borane, NH3BH3, has been extensively studied as a potential hydrogen storage material because of its high hydrogen content (19.6wt%) and relatively low decomposition...

Clays are porous materials and planned to be used as barrier material in radioactive waste repositories. In this context understanding of water and solute diffusion on different...

Our uSR measurements on superconducting Y1-xErxNi2B2C shows a slowing of the Er spin dynamics upon cooling to 2.5 K, but the depolarisation rate does not critically diverge and...

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...

We wish to investigate the evolution of the low-field ALC peaks with temperature of TMS-Pentacene, so we can extract the temperature dependent electron spin relaxation rate. Our...

Alkali-cluster intercalated fullerides (LixC60, NaxC60) proved to be suitable materials for solid state hydrogen storage. In these compounds the hydrogen is chemically absorbed...

In a previous experiment (RB910492) we have made preliminary measurements of the rates of addition of muonium to vitamins C and E, as suggested by the ISIS panel. These rates...

Antioxidants are very important molecules because they can prevent or slow down the oxidative damage to our bodies. When our bodies use oxygen, free radicals are released which...

We propose further zero-field muon spin depolarization measurements at temperatures above 300K in order to determine barriers for thermal diffusion of positively charged muonium...

Strong spin-orbit coupling (SOC) has often lead to exotic properties in otherwise banal pool of 'paramagnetic' heavy ion oxides. In this context d4 Ir systems are exciting...

The diamagnetic states formed by muon implantation in alkali halides are to be characterised, and their diffusion studied, by means of RF final-state analysis. The 90° pulse...

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...

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...

We propose an investigation of the magnitude and fluctuations of internal magnetic fields in Mn-doped ZnGeP2. This chalcopyrite structured semiconductor has a ferromagnetic (FM)...

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...

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...

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...

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...

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...
