We propose to develop and carry out a novel in situ SR/electrochemical technique to identify the mechanism underlying ferromagnetism in palladium bionanoparticles. We...

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...

Recently we have investigated Pr2Pd3Ge5 and Pr2Rh3Ge5 compounds which form in the orthorhombic structure. Pr2Pd3Ge5 exhibits two magnetic transitions at TN1 = 7.5 K and TN2 =...

In a recent series of successful experiments at PSI and ISIS we were able to demonstrate the possibility of measuring the rate of transfer of a small molecule (allyl alcohol)...

Tb2Ti2O7 is one of two compounds identified as potential quantum spin ices. As with other oxide pyrochlores the properties depend sensitively on the oxygen content. Most...

The spin relaxation rates of free radicals in solution can provide valuable information about the dynamics of molecular tumbling in solution, and solvent-radical interactions....

The origin of a mysterious pseudogap region in high-Tc superconductors is a challenging issue. It was proposed that the pseudogap is caused by a circulating-current order...

The current experiment proposes to identify and study the spin dynamics of the muon states formed in octabutoxy-phthalocyanine (oBu-H2Pc) using the avoided level crossing...

Previous muon experiments have identified a muonium state in the commonly occuring, but complex, beta rhombohedral form of elemental boron. To complement recent theoretical work...

The mechanism of action of inhalation anaesthetics such as N2O and the inert gases are unclear. Direct binding to receptor sites on membranes would rely on weak intermolecular...

Using the Emu spectrometer at ISIS we have recently studied charge carrier transport in the technologically important molecule 8-hydroxy-quinoline aluminium, by probing the...

Molecular ferromagnets offer great potential as they are synthesized at low temperatures and offer the possibility functionalization. Ni(TCNQ)2 is such a molecular ferromagnet,...

Our ongoing project to characterise radical scavenging by the green tea anti-oxidant EGCG and its D-ring analogue, (3,4,5-(OH)3-Bz) is near-complete. ALC-MuSR experiments on the...

This experiment aims at studying the magnetic behaviour of the molecular square complex {[Fe{B(pz)_4}(CN)_3]_2[Co(bik)_2]_2}(ClO_4)_2 . 3H_2O [B(pz)_4 = tetrapyrazolylborate,...

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...

In this proposal we propose to continue our investigation into the LaNiC2 non-centrosymmetric superconductors. Previously, we have shown that in this system time reversal...

We propose to characterise selected radical structures of the green-tea anti-oxidant flavenoid EGCG (& selected analogues), by DFT/post-HF computation and ALC-MuSR, towards...

ZrB12 is a cluster boride compound which is superconducting at 6K although the source of the pairing interaction appears to come from the Zr ions with the boron acting as a...

Superconductivity and the charge density wave (CDW) are two very different cooperative electronic phenomena. However, both occur because of Fermi surface instabilities and...

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...
