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

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...

Common d5 pyrochlore iridates, A2Ir2O7 or A2Ir2O6O’, are reported to have long range magnetic order based on muSR experiment. Only Pr2Ir2O7 has been identified as a metallic...

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...

One-dimensional (1D) S = 1/2 spin chains are a subject of long-standing interest, because conventional long-range ordering can be prevented and novel Luttinger-liquid phase may...

This is a continuation proposal describing an "in situ" muSR experiment on hydrogen storage materials. For the two previous beam-time allocated for RB1510262 and RB1520259, we...

We can trace the history of electrochemical cells just over two hundred years back to Luigi Galvani and Alessandro Volta¿s inventions, and perhaps more than a millennium further...

Rare-earth delafossites were recently proposed as promising candidates for the realization of an effective S = 1/2 quantum spin liquid on the triangular lattice [1, 2]. In...

In this proposal we wish to explore how the RF-uSR technique might be developed for measurements akin to FT-NMR. Our work will focus on the broadband excitation of paramagnetic...

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...

Lithium (Li) ion batteries is the most common battery technology but lately also sodium (Na) batteries are being considered. One reason is that the Li-reserves are limited and...

Materials containing triangular structures of magnetic moment are an important pathway to studying unconventional magnetic phenomena that arise from the geometrical frustration....

LiFePO4 is cathode material for Li ion batteries. One of the key functional properties is the Li-ion diffusion. Theoretical calculations showed that Li diffusion along the [010]...

Quantum phase transitions (QPT's) are phase transitions that are driven by zero-temperature quantum fluctuations, and are accessed by varying a non-thermal control parameter....

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...

Batteries are ubiquitous in everday applications but making them cheaper, safer, and able to store more energy could widen their use still further. Many rechargeable batteries...

One goal of our research into the nanoengineering of molecular magnets is a detailed understanding of the relationship between the structure and composition of a system and its...

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...

In recent years, the family of lead halide perovskite materials (e.g. MAPbI3) has attracted substantial interest due to their unique combination of properties and potential...

In recent years, nanoparticles have been a major source of interest in a wide range of fields. Our long term objectives are tuning the free radical reactivity on the surface of...
