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... -
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... -
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... -
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... -
The search and optimisation of Delta0 resonances in TIPS-Pentacene in solution
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... -
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... -
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... -
Magnetic phase transition in lightly doped LiGa1-xInxCr4O8
Magnetic frustration - the inability to mutually satisfy all magnetic interactions in a system - is the source of many interesting phenomena, including spin liquids and ices. In... -
Search for monopoles in spin ice via the exterior field distribution
Bramwell et al. have provided an elegant demonstration of dynamics in magnetic monopoles in spin ice measured by muons implanted inside the sample. However, it is likely that... -
Low temperature magnetic order and spin dynamics in Ho2Ir2O7
Ho2Ir2O7 has a cubic pyrochlore structure. Trigonal crystal fields at both the Ho and Ir sites create Ising-like moments that can order in a non-collinear arrangement with... -
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... -

In this proposal we plan to investigate the anomalous magnetism of Ce in recently discovered CeO0.5F0.5BiS2 and Sr0.5Ce0.5FBiS2 magneto-superconductors. The proposed compounds... -
Spin dynamics in the Tomonaga-Luttinger Liquid (TLL) State appeared in the Su...
The TLL phase is a quantum spin condensed state in the one-dimensional system. In the case of DIMPY system which is a quasi-one-dimensional organic magnet, the TLL phase is... -
muSR investigation of spin-orbit coupling driven magnetism of Ba3Zn1-xNixIr2O...
Strong spin-orbit coupling (SOC) in 5d transition metal oxides very often leads to unexpectedelectronic and magnetic ground state. While a nonmagnetic J=0 ground state can be...
