In a typical magnetic material the interactions between neighbouring magnetic moments will tend to lead to their ordered alignment throughout the entire structure as it is...

Recent investigations of physical properties of ACo2As2 (A = Ca, Sr, Ba) indicate that Co-based arsenides could be a potential parent compound like the parent AFe2As2. While...

Recently the discovery of superconductivity in the quasi-1D Rb2Cr3As3 with TC=4.8 K has attracted considerable interest. The unconventional superconductivity has been revealed...

Rare-earth tri-tellurides (RETe3, RE = Sc, Y, La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm) are materials with 2D electronic character and have a charge-density wave (CDW) phase...

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...

Lu3Os4Ge13 is an interesting superconducting system, with potentially unconventional physics. It is a low carrier density semi-metal, exhibiting superconductivity at 3.1 K. This...

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...

In recent work Moessner and colleagues have demonstrated that thermally induced defects in spin ice behave as emergent magnetic monopoles. Within the material there exist...

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...

Metallic systems with one-dimensional chain-like atomic structure can support unusual mechanisms for electron pairing leading to superconductivity. K_2Cr_3As_3 is one of a...

Recently, barlowite Cu4(OH)6FBr have been attracting much attention as a new kagome system with a Z2 topological order, which may yield spin liquid state at relative high...

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 this proposal we suggest an investigation of the time reversal symmetry breaking in the superconducting compounds YRuB2 and LuRuB2 with orthorhombic structure (space group...

In conventional superconductors gauge symmetry is broken, while in unconventional superconductors other symmetries may also be broken. There has recently been a great deal of...

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...

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...

Ternary compounds R5T4X10 crystallizing in primitive tetragonal structure (space group P4/mbm) present interesting physical properties. Of particular interests are the...

We propose to carry out a muSR study of the spin dynamics in two single crystal samples of Yb2Ti2O7. Both samples are notionally stoichiometric but they have been prepared using...

Molecular solids whose cooperative electronic properties are based purely on pi-electrons from carbon atoms offer a fertile ground in the search for exotic states of matter,...
