Investigation of the magnetic phases of the charge transfer compound CuTCNQ
The charge transfer compound CuTCNQ (TCNQ = 7,7,8,8-Tetracyanoquinodimethane) exhibits switching between two electrical resistance states when subject to an electric field. It... -
Proton dynamics in novel organic ferroelectric materials
The vast majority of known ferroelectrics are inorganic compounds such as barium titanate and potassium dihydrogen phosphate. Contrary to naïve expectation, ferroelectricity in... -
Surveying Hebel-Slichter peaks in conventional-ish superconductors
The presence of a Hebel-Slichter peak in NMR or µSR measurements just below the critical temperature of superconductors is taken to be strong evidence for conventional behaviour... -
Frustration-stabilised high-field skyrmions
Magnetic skyrmions are nanometric topological vortex-like spin textures that appear in select materials and have lately attracted a lot of attention due to their numerous... -
Investigating the superconducting pairing symmetry of heavy fermion supercond...
The first discovered heavy fermion superconductor CeCu2Si2 had been believed to have d-wave pairing symmetry for many years. However, recent experiments on CeCu2Si2 discovered... -
Iron-based superconductors with molecular spacer layers: probing Li diffusion...
All known iron-based superconductors comprise layers of FeAs or FeSe with some combination of group I, group II or lanthanide oxide layers, and usually some doping. To make... -
INS Determination of the Surface Properties of Nanoparticle Pollutants
Metal oxide nanoparticles are a form of pollution generated by a number of industrial procedures, and there is evidence that this class of nanoparticle can have a detrimental... -
Spin dynamics of the Heisenberg triangular antiferromagnet KCrO2
The members of the series ACrO2 (where A=Li, Na, K) comprise well-decoupled, highly ideal triangular planes containing isotropic spins. While the A=Li and Na materials have been... -
Spin Dynamics in the isotopically enriched spin ice 162Dy2Ti2O7
In an attempt to study the dynamics of Dy2Ti2O7 measured using muons we have made a sample of 162Dy2Ti2O7 where the 161 and 164 isotopes are reduced to a minimum (max. 0.6% of... -
Muon probes of hydrogen-bond network in supercooled water
Muon diamagnetic fraction in liquid water is known to decrease with decreasing temperature probably because its formation mechanism results from the structural alternation and... -
Investigating Magnetic Ordering in Ba2MnWO6 and Sr2MnWO6
Cubic double perovskites provide a rare example of an undistorted face-centred cubic lattice, made up of edge sharing regular tetrahedra. In Ba2MnWO6, antiferromagnetically... -
Influence of the cation disorder on the magnetic properties of underdoped cup...
We want to isolate the effects of doping, charge localization and local distortion on the transition from insulating antiferromagnet to superconducting metal in YBCO. We choose... -
Magnetism and superconductivity in hyperexpanded fullerides close to the Mott...
The fcc polymorph of the hyperexpanded fulleride Cs3C60 can be driven to a bulk suprconducting state without symmetry change by the application of pressure. Its Tc passes... -
Muonium in widegap oxides
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... -
Single crystal study of a-RuCl3, a quantum magnet on a honeycomb lattice
a-RuCl3 is a honeycomb lattice system which is thought to be close to a spin liquid state. The layers are weakly coupled and therefore the system is susceptible to stacking... -
Muon spin relaxation study of biskyrmions in MnNiGa
Skyrmions are chiral spin textures that exist in a variety of magnetic materials. These states are topologically non-trivial, which gives them stability expected to be useful... -
Muon Spin Relaxation study on Quantum Spin Liquid candidates Tm3Sb3M2O14 (M =...
Quantum spin liquid (QSL) state is a state that spins are highly entangled and frustrated even at absolute zero temperature, which has attracted lots of attentions due to its... -
Penetration depth in isovalent Ru substitution Ba(Fe$_{1-x}$Ru$_x$)$_2$As$_2$
The investigation of the recently discovered high-Tc superconductors based on iron pnictides, has attracted great attention. Much effort has been devoted to determining the... -
