One of us has recently found experimental evidence for unconventional superconductivity in a newly synthesized three-dimensional nearly antiferromagnetic metal, LaAg1−xMnx...

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...

CeRhIn5 is an antiferromagnetic itinerant magnet which illustrates a temperature and pressure interplay between antiferromagnetism and superconductivity. Recently, it has been...

Majorana fermion, proposed by Ettore Majorana in 1937, is a putative elementary spin-1/2 particle that is its own antiparticle. In condensed-matter systems, analogs of Majorana...

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...

Pure Ho2Ti2O7 exhibits spin ice beahviour. Studies of doped spin ice, replacing Ho with non-magnetic Y, suggest that the spin ice state is present even when the amount of doping...

The kappa structural phase of BEDT-TTF salts incorporating various anions X provides an extremely interesting series of layered-structure strongly-correlated materials, whose...

Quantum spin liquid (QSL) is an ordered spin state which has been destroyed by quantum fluctuations at low temperatures. Low energy excitations of spin liquids are charge...

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...

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...

Our recent µSR measurements on a polycrystalline sample of Ru7B3 has shown that this material is an excellent example of broken time reversal symmetry on entering the...

Spins on the kagome lattice are one of the most widely investigated topics in frustrated magnetism. This two-dimensional corner sharing triangular lattice offers a...

Recent discovery of superconductivity (SC) in the novel quasi-1D system A2Cr3As3 (A=K, Rb and Cs with TC ≈ 6.1 K, 4.8 K and 2.2 K, respectively) has attracted considerable...

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...

Time reversal symmetry (TRS) breaking in a superconductor is often taken as evidence of unconventional pairing states. The recent observation of TRS breaking in several...

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

Magnetic order is a property of crystalline materials which contain systems of coupled magnetic moments. In materials known as geometrically frustrated magnets there exist...
