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

This proposal is part of our project to investigate the unusual physics of 5d transition metal oxides. In particular, we are studying two samples of the chemical composition...

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...

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...

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

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...

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...

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...

PrOs4Sb12 is a 1.85 K superconductor. Its superconductivity shows unconventional behavior, and the originating mechanism remains unknown. One characteristic is an internal...

The spin ice compounds Dy2Ti2O7 and Ho2Ti2O7 have come to enormous attention in the past year with the observation of excitations resembling magnetic monopoles. Here we propose...

Here we propose measurements on a unique, newly synthesized series of coordination polymers based on chains of Cu2+ ions. These have been designed with the intention of...

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

PdTe2 was found to be superconducting below Tc = 1.7 K and a Type-II Dirac semimetal. A protected bulk Dirac point arises from a band inversion that occurs within the Te...

Shiomi et al. have prepared a nitronyl nitroxide radical-based compound which has a chiral packing of the molecular units. This is the first discovery of a purely organic chiral...

PrOs4Sb12 is a 1.85 K superconductor. Its superconductivity shows unconventional behavior, and the originating mechanism remains unknown. One characteristic is an internal...

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...

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...

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,...
