Muon spin dynamics in ZnSe
We intend to detail the muonium dynamics and investigate the interaction with charge carriers in n-type ZnSe. A doped ZnSe sample (resistivity=10^4 Ohm.cm, n=10^13 cm^-3) is... -
μSR study of the magnetic ordering in the S=1 linear chain compounds RbN...
The quasi 1-D magnets ANiCl3: A = Cs, Tl, order magnetically in two steps. A partially ordered state between TN1 and TN2 and a fully magnetic ordered state below TN2. RbNiCl3... -
Quantum spin ice physics in Pr-based pyrochlores
In order to explore quantum spin ice physics, we wish to focus on the non-Kramers Pr-based pyrochlores with general formula Pr2M2O7 (M =Sn, Zr, Hf). There is a recent... -
Tunneling and relaxation of the magnetization in Mn6 single molecule magnet
The Mn6 single molecule magnet shows to date the highest anisotropy barrier for a transition metal cluster. Low lying excited states in the energy level diagram of the molecule... -
Investigating the muon radical in Sulphur
Recent muon level-crossing measurements in the stable orthorhombic alpha-phase of sulphur indicate the existence of a radical state, with an interesting temperature evolution.... -
Models of the [FeFe]-hydrogenase active site: raising the symmetry
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... -
Muon spin relaxation studies of KTCNQ and related compounds
Potassium tetracyanoquinodimenthane (KTCNQ) undergoes a spin-Peierls (SP) transition at 396K where a transformation from uniform to dimerised TCNQ- molecules in 1D columns... -
RF MuSR in the gas phase: the Search for a Radical State
The main spectroscopic technique for studying radicals in solids and liquids, ESR, cannot usually be used to study radicals of more than 3-5 atoms in the gas phase due to strong... -
Partial freezing of a Kagome Magnet
Ever since the first published consideration of the ground state of a triangular lattice of Ising spins by PW Andersen in the 50's, the pursuit of materials with geometrically... -
Muon response to changes in the charge distribution of the components of a co...
We plan to confirm that the change in asymmetry on resonance in the ALC spectra seen in the subject complex dielectric during the previous rapid access proposal (RB1900028) is a... -
Organometallic Radicals
Avoided level crossing muon spin resonance (ALC-muSR) is an exceptional tool for determining the structure and probing the dynamics of radicals but there have been only a few... -

Understanding the spin-Peierls Transition in KTCNQ and derivatives
Motivated by work showing that magnetic coupling between TCNQ anions in potassium TCNQ (KTCNQ) can be changed simply by changing the aromatic substituents, we seek to qunatify... -
Unconventional superconductivity in quasi-1D K_2Cr_3As_3 (QLCR)
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... -
RF MuSR in the gas phase: The Search for a Radical State (RB920227)
The main spectroscopic technique for studying radicals in solids and liquids, ESR, cannot usually be used to study radicals of more than 3-5 atoms in the gas phase due to strong... -
µSR investigation of NaxLi12-xC60
An economy based on hydrogen as an energy carrier is one of the most promising solutions against the greenhouse effect problem, due to the large amount of energy produced by the... -
Muon States in Nanostructured Carbonaceous Materials
This experiment proposes the continuation of a study, initiated at J-PARC, on a new type of activated carbon material, with a pore structure and chemistry "tunable" in a manner... -
MuSR study on the hidden order in Irridates
Recently the 5d transition metal oxide Sr2IrO4 has attracted much attention due to its close analogy with high-Tc cuprates. A hidden broken symmetry phase, which is similar to... -
Investigation of muonium diffusion, states and charge cycles in vanadium dioxide
We propose a study to characterize diffusive motion of muonium, charge cycles and Mu0 states in vanadium dioxide (VO2) using zero and longitudinal field muon spin depolarization... -
Quantum tunnelling of muonium via radical states in molecular solids
The extreme quantum nature of muons and muonium in condensed matter is the result of having a mass that is nine times lighter than that of a hydrogen atom. While this quantum...
