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...

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 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...

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...

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

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...

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...

In SrHo2O4, the Ho3+ ions are arranged in a network of triangles and hexagons, and coupled with antiferromagnetic exchange interactions, this gives rise to geometric...

After the discovery of multiband superconductivity in MgB2 (Tc = 39.7 K) a number of studies have been made to understand the origin of superconductivity in this compound as...

It has recently been proposed that Ba2YMoO6 is the first example of an exotic valence bond glass (VBG), which is characterized by an amorphous arrangement of spin dimers and...

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

Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature....

In superconductors, the inversion symmetry of the crystallographic structure plays a central role in the formation of the Cooper pairs. The intermetallic compounds La7Pd3 and...

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...

Recently, we performed muSR measurements at the continuous muon source at PSI on the magnetic and superconducting properties of locally non-centrosymmetric SrPtAs. We find a...

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...

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...

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