We aim at exploring the ground state of new Cu2+ S=1/2 kagome compounds, isomorphic to the now-celebrated Herbertsmithite, namely CdCu3(OH)6Cl2 and MgCu3(OH)6Cl2. Due to the...

The bilayer ruthenate Sr3Ru2O7 is the first material found to have a quantum critical end-point and is believed to display ¿nematic electronic order¿. We have previously studied...

A triangular lattice occupies a special position in the quantum spin-liquid (QSL) physics. Although the triangular-lattice Heisenberg antiferromagnet is known to evade a QSL,...

Low-dimensional quantum magnetism continues to be of great theoretical and experimental interest as reduced dimensionality supports strong quantum fluctuations which can result...

The quasi-kagome Kondo lattice CeRhSn exhibits quantum criticality induced by geometrical frustration. Divergent Grüneisen ratios provide evidence for a zero-field QCP. The...

We have recently succeeded to synthesize pure-phase of K2CuCl2SO4 and Na2CuCl2SO4. In addition, we succeeded to grow the large single crystals (~ 10×10×10 mm3). K2CuCl2SO4 is a...

The noncentrosymmetric half-Heusler semimetals RTBi (R=rare earth, T=Pt, Pd) have recently been proposed, according to electronic structure calculations, as plausible 3D...

A new layered iridate material, Cu2IrO3, has been fabricated. This material is isostructural with the much-studied Na2IrO3 and has a nearly ideal honeycomb structure that should...

Our muSR study on Ce(Os1-xFex)2Al10 with x=0.4, which reveals long range magnetic ordering below 24K from the heat capacity, shows unexpected behaviour. The muSR spectra only...

The possibility of superconductivity in tetragonal FeS has attracted considerable interest because of its similarities to the FeSe superconductor. However, for a long time all...

Recently, a new family of ternary platinum phosphide superconductors have been synthesised with the chemical formula APt3P (A = Sr, Ca, and La, with Tc’s of 8.4, 6.6, and 1.5 K,...

Cr-based superconductors provide a playground to understand the pairing mechanism in unconventional superconductor as they are strong candidate for multiband triplet pairing...

In the layered iron-based superconductor YFe2Ge2, a high Sommerfeld ratio of order 100 mJ/mol K^2 and a T^3/2 temperature dependence of the electrical resistivity at low...

PdxTaSe2 series is an excellent system for the investigation of the interplay between CDW and superconductivity which shows quantum critical point for x = 0.1. Very recently, we...

Low-dimensional quantum magnetism continues to be of great theoretical and experimental interest, as reduced dimensionality supports strong quantum fluctuations which can result...

Systems that exhibit a high degree of anisotropy have been attracting considerable attention due to unique physical properties. Recently three superconductors (SC), BaIr2Ge7,...

A new family of FeAs superconductors have very recently (Autumn 2008) been discovered in which, rather than alternating rare earth oxide layers with FeAs layers (as for the new...

Layered superconductors have been attracted substantial attention since the discovery of the cuprate and Fe-based high-Tc superconductors due to the diversity in their crystal...

In superconductors, the inversion symmetry of the crystallographic structure plays a central role in the formation of the Cooper pairs. When inversion symmetry is broken, there...

Pyrochlore oxides of the type A2B2O7 (where A = trivalent rare earth, B = tetravalent transition metal element) can form geometrically frustrated magnets displaying a range of...
