This year Nobel Prize award to the discovery of graphene has evidenced the relevance of this material, which has outstanding physical properties and promising technological...

In this continuation proposal we will conclude our muon study of FeCrAs, a recently re-examined material that displays many of the above characteristics, suggesting that it is a...

Antioxidants are very important molecules because they can prevent or slow down the oxidative damage to our bodies. When our bodies use oxygen, free radicals are released which...

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 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...

During our previous experiment on HiFi (RB1320541) we measured the ALC spectrum of the Fe2(µ-pdt)(CO)4(PMe3)2 model hydrogenase complex over multiple temperatures. The spectra...

Fe3Sn2 is a rare example of an itinerant frustrated ferromagnet (Tc = 640K), with a non-collinear spin structure. It shows a large anomalous Hall resistivity in a low field of...

The transport of electrically charged quasiparticles plays a pivotal role in modern technology. In contrast, the transport of magnetic charges has barely been explored...

The fcc polymorph of the hyperexpanded fulleride Cs3C60 can be driven to a bulk suprconducting state without symmetry change by the application of pressure. Its Tc passes...

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

The mineral Libethenite, Cu2PO4OH, is an ideal system in which to study low dimensional quantum magnetism. The spin-gapped nature of this material has been the subject of...

HfNiSn is a semiconducting material with cubic crystal symmetry, and as such it should not show any anisotropy in electronic transport.However, at low temperatures we observe...

In order to meet the UK's commitment to reduce 80% of greenhouse gas emissions by 2050, it is necessary make major advances in efficient, clean and secure energy conversion and...

We propose a set of RF measurements on Silicon Carbide (polytype 6H) to identify and characterize the muonium species present below room temperature. One of the main goals of...

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...

Along with the titanate and stannate materials, Gadolinium Zirconate, Gd2Zr2O7, makes up a series of model pyrochlore systems characterized by a Heisenberg antiferromagnetic...

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)....

Ho2Ir2O7 has a cubic pyrochlore structure. Trigonal crystal fields at both the Ho and Ir sites create Ising-like moments that can order in a non-collinear arrangement with...

Previous ALC measurements of the Fe2(pdt)(CO)4(PMe3)2 and [Fe2(pdt)(CO)4(CN)2]2- (referred to as 1 and 2) model hydrogenase subsites have yielded some intriguing results (RB...
