We report on low-temperature heat-transport properties of the spin-1/2 triangular-lattice antiferromagnet Cs_{2}CuCl_{4}. Broad maxima in the thermal conductivity along the three principal axes, observed at about 5 K, are interpreted in terms of the

A number of recent experiments indicate that the iron-chalcogenide FeSe provides the long-sought possibility to study bulk superconductivity in the cross-over regime between the weakly coupled Bardeen--Cooper--Schrieffer (BCS) pairing and the strongl

Metal-rich, mixed copper−rhodium sulfide Cu3−δRh34S30 that represents a new Cu-filled variant of the Rh17S15 structure has been synthesized and structurally characterized. Copper content in the [CuRh8] cubic cluster was found to vary notably dep

The thermodynamics in spin-ice systems are governed by emergent magnetic monopole excitations and, until now, the creation of a pair of these topological defects was associated with one specific pair-creation energy. Here, we show that the electric d
