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...

Tb2Ti2O7 is one of two compounds identified as potential quantum spin ices. As with other oxide pyrochlores the properties depend sensitively on the oxygen stoichiometry. Most...

Organic superconductor lambda-(BETS)2GaCl4 has attracted a great interest due to the low dimensionality, strongly correlated nature since it is lying near the dimer-Mott...

Gaining control of the building blocks of magnetic materials will enable the design and growth of bespoke magnetic devices. However, the ability to tune the magnetic...

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...

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...

It is proposed to use ZF and TF muSR to study the low temperature, low field part of the phase diagram of Ba3CuSb2O9, a system with a uniform triangular lattice of S=1/2 Cu ions...

A randomly diluted ferromagnet has its transition temperature Tc suppressed to a quantum critical point. Between the Tc of the diluted material and that of the undiluted...

With the observations of spin ice behaviour in Dy2Ti2O7 and Ho2Ti2O7 the rare earth pyrochlores R2B2O7 have evolved as a hot topic of current research activities. In our effort...

Spins arranged on the kagome lattice are one of the most widely investigated topics in frustrated magnetism. In this context, the three-dimensional analogue of these systems,...

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...

Sr3Ru2O7 is an unusual layered oxide metamagnetic metal. It has been know for some time that the application of a large magnetic field (~8 T) perpendicular to the RuO2 planes...

It is proposed to use TF muSR to study the low temperature, low field part of the phase diagram of Ba3CuSb2O9, a system with a uniform triangular lattice of S=1/2 Cu ions that...

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 role and interplay of the different charge degrees of freedom remain a central issue in many unconventional superconductors. PdxTaSe2 series is an ideal system to study such...
