The charge transfer compound CuTCNQ (TCNQ = 7,7,8,8-Tetracyanoquinodimethane) exhibits switching between two electrical resistance states when subject to an electric field. It...

The presence of a Hebel-Slichter peak in NMR or µSR measurements just below the critical temperature of superconductors is taken to be strong evidence for conventional behaviour...

Magnetic cooling has recently become the focus of cooling system technology as it boasts important advantages in terms of power consumption and for the environment e.g. not...

In recent work Moessner and colleagues have demonstrated that thermally induced defects in spin ice behave as emergent magnetic monopoles. Within the material there exist...

We intend to perform an inelastic neutron scattering experiment on para-H2 adsorbed in L-Isoleucyl-L-valine (IV) microporous systems using the TOSCA spectrometer. IV is one of a...

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...

Metal oxide nanoparticles are a form of pollution generated by a number of industrial procedures, and there is evidence that this class of nanoparticle can have a detrimental...

In rare-earth containing metals, there is a strong competition between the tendency of these systems to magnetically order or form a superconducting state, mirroring in many...

The material Cu(1,3-benzenedicarboxylate) (C8H4CuO4) features structurally perfect kagome lattice planes of spin-1/2 copper2+ ions, with the separated by organic linkers. High...

Muon diamagnetic fraction in liquid water is known to decrease with decreasing temperature probably because its formation mechanism results from the structural alternation and...

To the best of our knowledge, there is no previous work on using muons to measure photo-excited states in organic semiconductors or related materials. Our photo-excitation ideas...

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...

Cubic double perovskites provide a rare example of an undistorted face-centred cubic lattice, made up of edge sharing regular tetrahedra. In Ba2MnWO6, antiferromagnetically...

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

We propose to measure the neutron diffraction pattern of a single crystal sample of SrEr2O4, using the WISH diffractometer. As the magnetic Er ions in this compound are linked...

We propose to carry out a muSR study of the spin dynamics in two single crystal samples of Yb2Ti2O7. Both samples are notionally stoichiometric but they have been prepared using...

This proposal is part of a long-range program aiming at determining the stable charge-stateconfigurations, site and impurity energy levels (donor and/or acceptor) of hydrogen in...

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 investigation of the recently discovered high-Tc superconductors based on iron pnictides, has attracted great attention. Much effort has been devoted to determining the...
