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...

We aim to investigate the antiferromagnetic ground state of Ba2LiOsO6 using neutron powder diffraction, determining both the magnetic ordering propagation vector, and the...

The spin ice compounds Dy2Ti2O7 and Ho2Ti2O7 have come to enormous attention in the past year with the observation of excitations resembling magnetic monopoles. Here we propose...

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...

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...

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...

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...

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...

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...

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...
