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...

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...

Tissue Factor (TF) is the membrane protein responsible for the initiation of the blood coagulation process [1]. In case of a vessel injury, the TF is exposed to the blood stream...

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...

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...

k-ET_2Cu_2(CN)_3 provides an excellent experimental system for studying the 2D S=1/2 frustrated triangular lattice Heisenberg model. A spin-liquid state persists in this system...

We propose longitudinal field muSR on a 2D molecular magnetic system which has been suggested to have an unusual B-T phase diagram. Our goal is to probe the transition from...

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...

Among the rare earth titanates and stannates cristallising in the pyrochlore crystal structure, Tb2Ti2O7 is a singular system since its ground state is believed to be a spin...

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...

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

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...

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...

Topological insulators are 3D materials with a band gap in the bulk-electronic structure but with gapless, delocalized, surface states. The most studied topological insulator is...

In 2005 we carried out muon spin relaxation (muSR) experiments in Pr(Os1-xRux)4Sb12 alloys at KEK, Tsukuba, Japan, to investigate the time-reversal symmetry breaking found in...

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...
