Skyrmions are topologically protected, vortex-like nano-sized objects which have been shown to exist in the spin textures of a range of magnetic materials. As we have recently...

We propose to study PdxIrTe2, which evolves from a charge-orbital density wave state to a superconducting state with doping. It has a similar structural motif, doping-dependent...

Valence tautomers are bistable molecules of potential interest for magnetic storage and spintronic devices which can be switched between a low-spin and a high-spin state by...

SrAuSi3 crystallizes in a BaNiSn3-type structure which has no inversion symmetry in real space and also a superconductor with a Tc of 1.54 K. SrAuSi3 includes Au as a principal...

We propose to investigate the roles of the spin-orbit interaction and geometrical frustration in stabilising a quantum spin liquid phase (QSL) in some iridate systems. µSR is a...

We propose to characterize the basic muonium/hydrogen configurations in selected rare-earth sesquioxides with the basic crystallographic structures: neodymium oxide (hexagonal A...

Despite many previous attempts, Sr4Fe6O12 (the expected fully reduced composition for Sr4Fe6O13-x) has not been synthesised. It is of interest because it is believed to contain...

Hydrogen abstraction reactions are key steps in free radical mechanisms that dominate the combustion and atmospheric chemistry of the alkane hydrocarbons and, as such, merit...

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...

Open p-shell anionic compounds are model systems where the interplay between charge, lattice, orbital, and spin degrees of freedom leads to complex magnetic behavior. In the...

We propose to continue laser spectroscopy measurements of the muonium (Mu-) centres in n-type doped silicon carbide. Scanning a wide wavelength range, and changing the relative...

The study of organic ferroelectrics based on mixed-stack charge-transfer salts is currently a rapidly developing research field. These materials attract interest as highly...

Here we propose to use muon spectroscopy to study the diffusion of sodium in hard carbon anode materials of various porosity for sodium ion batteries. Hard carbon is the most...

We propose to study the evolution of ZF-muSR and low-field (100 G) TF-muSR spectra and relaxation times across the charge ordering temperature T0 = 140 K of RbFe2As2 iron based...

We have recently performed muon measurements on a member of a new class of multiferroic materials. We have shown that there is hysteretic behaviour to the internal field...

Ice VI is likely to be a major mantle mineral in the interiors of large icy moons in our solar system, and in large icy extrasolar planets. It is also a common accessory phase...

The extreme quantum nature of muons and muonium in condensed matter is the result of having a mass that is nine times lighter than that of a hydrogen atom. While this quantum...

This proposal seeks to conduct total-scattering studies on thallium and caesium azides to investigate the effect of temperature on the atomic motions, particularly of the azide...

Hydrogen abstraction reactions are key steps in free radical mechanisms that dominate the combustion and atmospheric chemistry of the alkane hydrocarbons and, as such, merit...

In this proposal, we wish to study the origin of the multiferroic nature in Sr4Fe2(CO3)O6. In the magnetization data, antiferromagnetic (AFM) ordering appears at TN = 340 K and...
