Exploiting spin coherence phenomena in quantum materials is both technologically and fundamentally relevant, particularly in view of recent developments in quantum computing....

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...

The frustrated pyrochlore Er2Ti2O7 is a rare example of a magnetic system in which quantum fluctuations are capable of selecting a unique ground state out of the macroscopically...

Pure Ho2Ti2O7 exhibits spin ice beahviour. Studies of doped spin ice, replacing Ho with non-magnetic Y, suggest that the spin ice state is present even when the amount of doping...

The system 1T-TaS2 is a charge density wave (CDW) insulator below 180 K that has one residual spin 1/2 for every 13 Ta atoms in the modulated CDW structure. These spins and...

Small-sized metal nanoparticles (NPs) are of long standing interest to both magnetism and heterogeneous catalysis. Muon studies of Au NPs encapsulated in 'SBA-15' silica are...

In view of the interesting magnetic properties observed in CeTSi3 (T=Pt and Pd) and superconductivity in LaPdSi3 (TSC= 2.6 K), as well as the theoretical interest in...

The investigation of electron correlations in intermetallic alloys is fascinating. At times, depending on the nature and strength of correlations, the compounds exhibit...

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...

Nonmagnetic impurity substitutions impact on superconducting properties in various ways depending on the pair-breaking mechanism. The aim of the proposed experiment is to...

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...

Anderson localization is a general phenomenon of wave physics, which was originally proposed for electrons in a crystal, but later was also observed for light, microwaves,...

The molecular magnetic system Mo3S7(dmit)3 is a semiconductor with a charge gap of around 100 K and no magnetic transition or spin freezing down to 2 K. In the crystal structure...

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...

The [FeFe]-hydrogenase enzymes are some of the best catalysts know for generating hydrogen. We have an ongoing programme to understand how their chemistry works, and to...

In centrosymmetric heavy-fermion (HF) superconductors Cooper pairs have either singlet or triplet symmetry. Recently a handful of non-centrosymmetric Ce-based HF compounds have...

An important element of the work associated with the current Framework Programme 7 Joint Research Activity (JRA) for muons is the development of gas sample pressure cells...
