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

These half-Heusler compounds are also semi-metals, with low carrier densities and non-trivial topological features. The crystal structures are also non-centrosymmetric, which is...

Today, about seventy years after Laves, there exists a fairly good knowledge about the basic structural principles of Laves phases but many questions still remain. AMn-type...

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...

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...

Our recent musr studies on CeT 2Al10 (T=Os and Ru) reveal a clear sign of long range magnetic ordering below 28 K in both the compounds. More interestingly the frequency...

In view of the interesting magnetic properties observed in CeTSi3 (T=Pt and Pd) and superconductivity in LaPdSi3 (TSC= 2.6 K), as well as the theoretical interest in...

Spinels, which have formula AB2X4 and crystallise in the cubic space group, exhibit a rich landscape of structural, magnetic and electronic properties. However, superconducting...

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...

The development of spontaneous fields in the superconducting state in non-centrosymmetric superconductors is shown by a number but not all such superconductors. Our recent...

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...

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...

Superconductivity in systems which lack inversion symmetry is expected to give rise to a host of unconventional effects, including mixed parity ground-states, and the formation...

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...
