All known iron-based superconductors comprise layers of FeAs or FeSe with some combination of group I, group II or lanthanide oxide layers, and usually some doping. To make...

The members of the series ACrO2 (where A=Li, Na, K) comprise well-decoupled, highly ideal triangular planes containing isotropic spins. While the A=Li and Na materials have been...

Here we propose measurements on a unique, newly synthesized series of coordination polymers based on chains of Cu2+ ions. These have been designed with the intention of...

Shiomi et al. have prepared a nitronyl nitroxide radical-based compound which has a chiral packing of the molecular units. This is the first discovery of a purely organic chiral...

Muon spin relaxation is a remarkably powerful tool for discovering magnetic order in quasi-one-dimensional magnetic chain compounds, particularly when the weak interchain...

NMR has become an extremely sophisticated experimental technique because of the use of pulse sequences which allow the control and manipulation of a nuclear spin system or...

Bramwell et al. have provided an elegant demonstration of dynamics in magnetic monopoles in spin ice measured by muons implanted inside the sample. However, it is likely that...

A series of cyanide-bridged molecular magnets incorporating chiral ligands will be invstigated using muon spin relaxation. The magnets combine Ni(II) with M(III) (M=Fe,Cr,Co)....

The magnetic properties of a Terbium single ion magnetic system will be studied using implanted muons. The system is based on a polyoxometallate ion that provides good isolation...

Muon spin relaxation will be used to study the dynamical properties of the polymer polydimethylsiloxane. This has emerged as an excellent model system for the study of polymer...

Many strategies have emerged in recent years in the quest to design and synthesize functional materials which show cooperative properties. A particularly successful route to new...

In a recent letter to Nature, Boothroyd and coworkers have shown that the well known hour-glass spectrum, previously observed in some cuprate materials, occurs in a hole doped...

Repolarisation and level crossing resonance will be studied for several different oxalate compounds where muon radical states are known to be formed. Such compounds form a...

Work on the iron halides FeX2 has led to the models of A-type antiferromagnetism and the tricritical point in magnetic systems. Here we wish to carry out decoupling experiments...

Traditional high-temperature synthesis techniques can be used to vary the composition of K{1-x}Fe{2-y}Se2 up to certain limits. We have found a way to extend the limits on the K...

In 2012 we demonstrated that molecular spacer layers could be intercalated in between FeSe layers resulting in a dramatic enhancement of the critical temperature: FeSe is itself...

Spin ladders present a class of low-dimensional quantum magnets that occupy a regime of rather subtle behavior which lies between the stark extremes of a one-dimensional chain...

The new molecular magnet bis(2,3-dimethylpyridinium) tetrabromocuprate (DIMPY) is a strong-leg spin ladder with a quantum critical point at 3.0(3) T separating a low-field...

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

The fluorinated ionomer Nafion is a material that provides efficient proton conducting membranes for application in important technological areas such as hydrogen fuel cells....
