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...

The Mn6 single molecule magnet shows to date the highest anisotropy barrier for a transition metal cluster. Low lying excited states in the energy level diagram of the molecule...

We propose to explore the low energy excitation spectrum of the LiNiVO4, a system which we believe is a previously unobserved realization of a random distribution of 1D...

EuO is a model ferromagnet, with great potential in spintronics, but also of great interest from a theoretical point of view. Here we propose to study the magnetic proximity...

We propose a MuSR study of the magnetism in Mn-doped ZnGeP2 during this round of experiments using muon spin depolarization measurements in a longitudinal magnetic field. This...

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....

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...

We propose a continuation of longitudinal muon spin depolarization measurements on mid-range SiGe alloys where a direct observation of T-site ionization is not possible because...

Dy2Ti2O7 is a pyrochlore antiferromagnet that has a partial magnetization plateau between 0.1 and 0.9T for magnetic fields applied along the [111] direction. This represents a...

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...

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...

Continued investigation of magnetic fluctuations in the Mn-doiped chalcopyrite semiconductor ZnGeP2 is proposed using LF-MuSR depolarization rates. Due to ferromagnetism above...

Ca3CoMnO6 has alternating ions in ferromagnetic Ising chains that are antiferromagnetically coupled on a triangular lattice and realizes an important model in frustrated...

Two molecular magnetic systems are considered which show low-temperature ordered states. One of them is F4BImNN, a nitronyl nitroxide radical magnet, an excellent realization of...

This proposal seeks neutron diffraction beamtime to study two important systems. We have demonstrated that monofluorophosphate (PO3F) can be substituted into gypsum (CaSO4.2H2O)...
