The combination of strong magnetic frustration and low spin found in the S=1/2 quantum antiferromagnet is believed to lead to non-classical magnetic behaviour, and in particular...

Our previous studies of superconducting LiFeAs derivatives revealed a significant difference in Uemura scaling compared with all other studied pnictides. This experiment is...

It has been suggested that within green dipotase there the magnetism is dominated by quantum flucuations but evidence for this is not definitive. This means that in this...

Geometrically frustrated magnetic systems provide a plethora of opportunities to stabilize exotic ground state manifolds and have been at the forefront of current experimental...

Topological physics was the subject of this year's Nobel Prize for Physics and over forty years after the groundbreaking work of Kosterlitz, Thouless and Haldane, remains an...

The magnetic ground state of a compound containing higher d-orbital (4d/5d) is fascinating due to its various competing effects like extended orbital, pronounced crystal field...

We aim to perform zero and longitudinal field muon spin relaxation measurements in order to investigate anomalous spin dynamics effects observed in EuFe2(As1-xPx)2 with x=0.20...

Lead iron niobate, PbFe${1/2}$Nb${1/2}$O$_{3}$ (PFN), is a multiferroic material exhibiting paraelectric to ferroelectric and paramagnetic to G-type antiferromagnetic...

Spin ice materials exhibit novel magnetic behaviour because of their atomic interactions and geometric constraints of the crystal lattice. This novel behaviour takes the form of...

A new family of FeAs superconductors have very recently (Autumn 2008) been discovered in which, rather than alternating rare earth oxide layers with FeAs layers (as for the new...

In centrosymmetric heavy-fermion (HF) superconductors Cooper pairs have either singlet or triplet symmetry. Recently a handful of non-centrosymmetric Ce-based HF compounds have...

By the virtue of having an entangled ground state the Heisenberg spin ½ chain systems provide a suitable perform to test multi-qubit quantum information protocols. There have...

The new compound Li3Mg2RuO6 exhibits interesting structural and magnetic properties. The Ru5+ sublattice is intrinsically frustrated : chains, along various [110] directions, of...

In physics, frustration describes a situation where a system is unable to satisfy all of its internal interactions because of the geometry of its atomic structure. The most...

We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One...

Organic semiconductors have been of major interest in recent years. Amplified by the transition from fundamental physics to new commercial products and technologies, this new...

During the past decades, weakly coupled spin cluster systems have attracted much attention due to the possibility of observing concomitantly zero-dimensional quantum and...

Magnetism and superconductivity compete and coexist in many of the high temperature superconductors, and the newly discovered iron arsenides are no exception. Muon-spin rotation...

The unconventional filled skutterudite superconductor, PrPt4Ge12 (Tc~7.9K), was recently discovered, for wihch zero field muon spin relaxation (ZF-MuSR) experiments reveal that...

We have prepared a new family of electron-doped oxypnictides \RFeF\ with the same average Rare Earth radius as that yielding the highest superconducting Tc to date, i.e. the...
