We have performed further measurements on Dy2Ti2O7 and confirmed the observation of magnetic charge transport. Given the time constraints of our previous experiment not all...

The frustrated pyrochlore Er2Ti2O7 is a rare example of a magnetic system in which quantum fluctuations are capable of selecting a unique ground state out of the macroscopically...

One-dimensional (1D) S = 1/2 spin chains are a subject of long-standing interest, because conventional long-range ordering can be prevented and novel Luttinger-liquid phase may...

Recently, superconductivity has been discovered in a number of materials whose lattices lack inversion symmetry, with important implications for the symmetry of the...

Rare-earth delafossites were recently proposed as promising candidates for the realization of an effective S = 1/2 quantum spin liquid on the triangular lattice [1, 2]. In...

Quantum spin liquids (QSLs) are intriguing states of matter in which quantum fluctuations are sufficiently strong to destroy any long-range magnetic order. To date, one of the...

We intend to perform the magnetic field penetration depth \lambda measurements on theoxygen reduced and Nb-doped SrTiO_3 -- the first oxide superconductors where two-gap...

One goal of our research into the nanoengineering of molecular magnets is a detailed understanding of the relationship between the structure and composition of a system and its...

Pyrochlore magnets of formula R2Ti2O7 or R2Sn2O7 constitute the paradigm for geometrical frustration on a 3D lattice. Spinel compounds CdR2X4, where the R sublattice forms a...

Using nitronyl nitroxide radicals it is possible to prepare purely organic ferromagnets without inclusion of any transition metal or lanthanide ions. Muons are uniquely...

We will examine the impact of metal-halide hydrogen bond motifs and their ability to provide low-dimensional superexchange pathways. Specifically, we wish to investigate two new...

Cs3C60 is driven to a bulk superconductor without symmetry change by the application of pressure. Tc passes through a maximum of 38 K at 6 kbar. We have recently isolated the...

Nonmagnetic impurity substitutions impact on superconducting properties in various ways depending on the pair-breaking mechanism. The aim of the proposed experiment is to...

Cu-BHT exhibits perfect kagome lattice of Cu2+ and previous combined magnetization and specific heat results suggested the presence of strong spin fluctuations. If there are...

There has been a great deal of interest in non-centrosymmetric superconductivity, mainly induced by the discovery of CePt3Si. The presence or lack of inversion has important...

Our recent research of various Th-bearing systems revealed bulk superconductivity in ThIrSi3, ThIr2Si2 and ThCoSi. The critical temperatures determined from the resistivity and...

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

Recently, Eckert and co-authors synthesised osmium based two superconductors, NbOsSi and TaOsSi, and found that these compounds exhibit superconductivity below a transition...

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

Quantum spin liquid (QSL) is a novel state of matter where the spins are highly entangled with one another but fluctuate strongly down to zero temperature. It may be associated...
