A Local Magnetic Study of the Unusual Phase Behaviour of Sr2YbMoO6
As part of a project to develop new electronic materials based on the coupling of electronic and structural properties in new perovskites we have been investigating the... -
Na4Ir3O8: a spin liquid, a valence bond crystal, or something else?
Spins on the kagome lattice are one of the most widely investigated topics in frustrated magnetism. This two-dimensional corner sharing triangular lattice offers a... -
High Temperature Spin Transition in LaCoO3
We aim to continue our investigation of the high temperature magnetic interactions in LaCoO3. Our previous experiment has confirmed magnetic susceptibility data, with a change... -
Ion dynamics in Sodium and Potassium Cobalt Dioxides
We found that muSR detects Li-diffusion in LixCoO2, LiNiO2, Lix(NiCoMn)O2 and LiFePO4 through a dynamic behavior of nuclear field relaxation. Very recently, we have also found... -
muSR study of frustrated magnets with a spinel structure
Pyrochlore magnets of formula R2Ti2O7 or R2Sn2O7 constitute the paradigm for geometrical frustration on a 3D lattice. Spinel compounds CdR2X4, where the R sublattice forms a... -
MUSR investigations of the spin-liquid ground sate in the new kagome lattice ...
Unveiling quantum effects in materials at low temperatures, such as quantum spin-liquid behavior, have been a central task in condensed matter physics. A two-dimensional kagome... -
muSR in the presence of significant spin-orbit coupling
The great majority of known muonium defect centres and muonium substituted organic radicals have essentially spin-only magnetism, with few exhibiting any noticeable departure... -
Elucidating the magnetic nature of alpha-RuCl3 - a rediscovered honeycomb system
Materials with layered honeycomb structures have been subject to a strenuous research effort in the past couple of years in an effort to find materials that exemplify the... -
Copy of: Towards a Method of Quantifying Electrophilicity and Nucleophilicity
Our understanding of chemical reactivity is founded on the fundamental concepts of Electrophilicity and Neucleophilicity. There are a number of attempts of limited applicability... -
Control of the electronic state in new pnictide superconductors using doping
The properties of pnictide superconductors can be controlled exquisitely by chemical doping. We have identified some key systems in which to explore this effect which should... -
BaCu2(Si1-xGex)2O7 - A spin 1/2 chain material with tunable inter-chain inter...
BaCu2Ge2O7 is reported to be a one dimensional Heisenberg antiferromagnet, with three dimensional long range order at low temperatures due to small antiferromagnetic... -
Li-diffusion dynamics in high voltage fluoride-containing cathodes
Research on positive insertion electrodes for high performance batteries has seen immense interest in fluoride containing compounds, since higher operating potentials can be... -
Molecular diffusion in supercooled liquid water
Following our μSR experiment on liquid water (RB1720491) we propose to measure molecular diffusion coefficient (the sum of the diffusion coefficients of muonium and oxygen... -
Li diffusion in Li-Mn-O (continuation)
This proposal describes a continuation muSR experiment on Li-Mn-oxides to see Li diffusion, because muSR is a powerful technique to detect it in the compounds containing... -
Chasing the hydrogen-saturated defects in tungsten with Muon spectroscopy
The structure and dynamics of hydrogen (H) defects in tungsten recently become a topic of major interest since this metal has been chosen as shielding material for the next step... -
Determination of a reaction area of cathode in a liquid electrolyte by muSR
In order to estimate a reliable reaction area (a_r) between cathode and liquid electrolyte in a Li-ion battery, we wish to propose a muSR experiment on a charged-state cathode... -
Muon radicals in the metastable phases of Sulphur
Following our investigation of alpha-orthorhombic sulphur, we will measure level crossing spectra of some other allotropes and phases, to find if the muon radical observed in... -
MuSR study of a spin gap opening associated with an extraordinary magnetovolu...
We have discovered an unusual magnetovolume effect in the 6H-perovskite oxides Ba3BiIr2O9 and Ba3BiRu2O9. These compounds contain isolated face-sharing bi-octahedral dimers... -
Determination of diffusing species in LiFePO4 with negative muons
By means of a positive muon spin rotation and relaxation (mu+SR) technique, we have investigate Li and Na ion diffusion in many battery materials. Among them, it was found that... -
Field induced spin Luttinger liquid phase in a spin ladder
Spin ladders present a class of low dimensional quantum magnets that occupy a regime of subtle behaviour which lies between the stark extremes of a one-dimensional chain or...
