The charge transfer compound CuTCNQ (TCNQ = 7,7,8,8-Tetracyanoquinodimethane) exhibits switching between two electrical resistance states when subject to an electric field. It...

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...

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...

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...

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...

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...

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...

Cubic double perovskites provide a rare example of an undistorted face-centred cubic lattice, made up of edge sharing regular tetrahedra. In Ba2MnWO6, antiferromagnetically...

FeSe is a superconductor below 8.5 K. Very recently, we have found superconductivity in a wide compositional range in a series of layered lithium iron selenide hydroxides....

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...

a-RuCl3 is a honeycomb lattice system which is thought to be close to a spin liquid state. The layers are weakly coupled and therefore the system is susceptible to stacking...

A2Mo3As3 (A = alkali metal) is a brand-new novel family of molybdenum arsenide based quasi-one-dimensional (Q1D) superconductors with a transition temperature between 10.4 to...

BiFeO3 is a room temperature multiferroic, displaying both ferroelectric and antiferromagnetic (AFE) ordering. x-BiFeO3 - (1-x)-PbTiO3 is also multiferroic at room temperature...

Every new triangular lattice (TL) antiferromagnet attracts considerable attention since they usually display rich physics due to the inherent frustration and degenerate ground...

Understanding superconductivity has been a goal of condensed matter scientists since its discovery. However, there has been a continual discovery of new materials that challenge...

The question of whether the spin transport in an S=1/2 Heisenberg antiferromagnetic chain is ballistic or diffusive remains intensely discussed theoretically and studied...
