Recent progress in the field of molecular magnetism has shown the potential for gaining control over the structural building blocks of molecular materials in order to engineer...

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...

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...

This proposal is part of a long-range program aiming at determining the stable charge-stateconfigurations, site and impurity energy levels (donor and/or acceptor) of hydrogen in...

Graphene has recently received widespread attention, after the discovery of its stability as a 2Dcrystal at ambient conditions and thanks to a wealth of possible applications....

Radio-frequency muon spin resonance is an exceptional technique for studying free radicals, but it has not been applied to study radicals in the gas phase. In a previous...

A study of the ground state of the Ce5Rh4Sn10 is proposed. Compound belongs to the heavy fermion system with two magnetic phase transitions at 1.4 K and 4.3 K. While the...

The combination of magnetic frustration and low magnetic moment leads to non-classical magnetic behaviour such as spin liquid states. We have prepared polycrystalline samples of...

CeIr3Si2 reveals highly anisotropic bulk properties with two magnetic transitions at TN1 ~ 3.9 K and TN2 ~ 3.1 K. The overall crystal electric field (CEF) splitting of the J=5/2...

The intermetallic family R5T4 (R = rare earth, T = Si or Ge) exhibit a wide range of magnetic phenomena (eg., magnetic order, GMR, and enhanced magnetocaloric effect) which are...

Tb2Ti2O7 is a pyrochlore antiferromagnet that has previously been viewed as a spin liquid. This description fails to describe key features of its physics and more recently the...

We propose to characterize the basic muonium/hydrogen configurations in selected rare-earth sesquioxides with the basic crystallographic structures: neodymium oxide (hexagonal A...

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...

Potassium tetracyanoquinodimenthane (KTCNQ) undergoes a spin-Peierls (SP) transition at 396K where a transformation from uniform to dimerised TCNQ- molecules in 1D columns...

Metallic systems with one-dimensional chain-like atomic structure can support unusual mechanisms for electron pairing leading to superconductivity. K_2Cr_3As_3 is one of a...

We propose a set of measurements using the HiFi spectrometer in which muon level-crossing resonances are used to probe the internal field inside antiferromagnets in which the...

Our recent experiment showed that muons implanted into black phosphorus (the most stable allotrope of the element, with a low band gap of 0.3eV) are apparently diamagnetic, with...

Frustrated compounds belonging to the pyrochlore family have attracted significant interest as they can host a huge variety of exotic phases. In order to explore the rich phase...

We have recently synthesised the novel iridocuprate IrSr2Sm1.15Ce0.85Cu2O10. This material exhibits a complex temperature dependence of the magnetic susceptibility with multiple...
