The relative importance of factors affecting the low temperature ALC spectra of organic molecular systems such as polymers and small molecules is a topical issue. Polybutadiene...

The quasi-two-dimensional molecular series kappa-(BEDT-TTF)2X exemplifies the complex interplay of collective phenomena that occur in correlated electron systems. Many of the...

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

We will use POLARIS to determine the structures of the high temperature superconducting intercalates obtained by the reactions between FeSe and deuterated ammonia solutions...

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

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...

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...

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...

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...

We will use the high resolution of HRPD and the excellent long d-spacing data available on OSIRIS to investigate the phase transitions in Sr1-xNaxFe2As2 which are associated...

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...

Here we propose to investigate the fluroide containing compounds - AgF2, CuF2 and Cs2CuF4. By taking advantage of the F-mu-F coupling wich occurs in these compounds, we will...

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...

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...

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...

We propose to determine the spin gap in TiPO4, to do this we will carry out a zero-field temperature scan from 5 to 150 K and anticipate focusing our measurements on the region...

We propose muSR studies on superfluid density in the overdoped La2-xSrxCuO4 (LSCO). The Hayden group (Bristol) has been growing high-quality LSCO single crystals, and performed...

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...

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...

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)....
