Non-centrosymmetric superconductors (NCS) are believed to be good candidates for unconventional superconductivity. In particular, there is the possibility of Cooper pairs with...

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...

The main purpose of this investigation is to discern the localized and itinerant contributions in the ferromagnertic superconductor UIr.Field dependent MuSR measurments up to...

Thermal, magnetic, neutron and muSR measurements all point towards a gapless or almost gapless spin liquid ground state for the triangular lattice spin system of S=1/2 Mo3...

The ternary intermetallics, which crystallise in the ThCr2Si2 structure, have been extensively studied mainly because these materials offer a rich variety of exotic ground...

Recent progress in the field of molecular magnetism has shown the potential for gaining control over the structural building blocks of molecular materials in order to engineer...

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...

The discovery of superconductivity in ThCr2Si2 type tetragonal Fe-based compounds (i.e. YFe2Ge2) have generated considerable interest. Recently we found bulk superconductivity...

This proposal plans to investigate the destruction of superconductivity by inter-band scattering in Lu_2Fe_3Si_5 doped by Y and Dy. Recent muon spin rotation studies have shown...

In some materials, the onset of superconductivity is accompanied by the spontaneous appearance of small magnetic fields. This is a signature of broken time-reversal-symmetry...

This proposal describes an in situ muSR experiment on a hydrogen storage material, MgH2. This is because MgH2 attracts a special attention due to the fact that the hydrogen...

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...

Magnetic properties of graphitic compounds are of current interest for both theoretical and experimental research in the fields of condensed matter physics and magnetism. In the...

In rare-earth containing metals, there is a strong competition between the tendency of these systems to magnetically order or form a superconducting state, mirroring in many...

In most unconventional superconductors, the importance of antiferromagnetic fluctuations is widely acknowledged. In addition, cuprate and iron-pnictide superconductors often...

Radio-frequency muon spin resonance is a powerful technique for studying free radicals and their reaction kinetics, but it has not yet been used to study complex reactions in...

Our uSR measurements on superconducting Y1-xErxNi2B2C shows a slowing of the Er spin dynamics upon cooling to 2.5 K, but the depolarisation rate does not critically diverge and...

This year Nobel Prize award to the discovery of graphene has evidenced the relevance of this material, which has outstanding physical properties and promising technological...

In this continuation proposal we will conclude our muon study of FeCrAs, a recently re-examined material that displays many of the above characteristics, suggesting that it is a...

Antioxidants are very important molecules because they can prevent or slow down the oxidative damage to our bodies. When our bodies use oxygen, free radicals are released which...
