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...

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...

Strong orbital mixing resulting from local distortions in the crystal field can mix higher energy orbital states with the ground state. We propose to characterise this mixing in...

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...

Cubic double perovskites provide a rare example of an undistorted face-centred cubic lattice, made up of edge sharing regular tetrahedra. In Ba2MnWO6, antiferromagnetically...

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...

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...

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...

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...

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...

We propose muSR studies on superfluid density in the overdoped La2-xSrxCuO4 (LSCO). The Hayden group (Bristol) has been growing high-quality LSCO single crystals, and performed...

We have been recently successful in isolating the fcc polymorph of the key hyperexpanded fulleride Cs3C60 - this phase can be driven to a bulk suprconducting state without...

The effect of isotope exchange on the Néel temperature in the cuprates was neer determined because it was impossible to perform relaible isotope exchanges in the parent...

Many strategies have emerged in recent years in the quest to design and synthesize functional materials which show cooperative properties. A particularly successful route to new...

We are currently investigating Haldane spin-chain compounds [PRB 2017] of the type R2BaNiO5 (R = rare earth) using bulk measurements and have found the multifunctional...

Repolarisation and level crossing resonance will be studied for several different oxalate compounds where muon radical states are known to be formed. Such compounds form a...

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...

Here we propose to investigate the fluroide containing compounds - AgF2, CuF2 and Cs2CuF4. By taking advantage of the F-mu-F coupling wich occurs in these compounds, we will...

RT2Al10 is a new series of rare-earth-based ternary aluminide compounds that show a variety of magnetic phenomena. This proposal is for a muSR study on three of its members to...

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...
