Potassium TCNQ is an stoichiometric organic based salt that undergoes a spin Peierls (SP) transition at approximately 390 K. Much research has been conducted on this system in...

BiCoO3 is a perovskite type material recently prepared by high pressure-high temperature synthesis in Kyoto. It has a distorted acentric perovskite structure with order of high...

An all solid state lithium ion battery (SSLIB) has an advantage in electrical capacity compared to the popular lithium ion battery (LIB) using a liquid electrolyte. However, a...

Spin ice materials exhibit novel magnetic behaviour because of their atomic interactions and geometric constraints of the crystal lattice. This novel behaviour takes the form of...

We propose to study two phases of Na-NH3 intercalated FeSe which have distinct values of Tc, both close to 40 K, but different concentrations of NH3 and quite distinct crystal...

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 origin of the Invar effect, whereby certain ferromagnetic alloys exhibit near zero thermal expansion around room temperature is still not properly understood. Although the...

Skyrmions are topologically protected vortex-like spin textures, and have been attracting increasing attention due to their potential technological applications for spintronics....

Rare-earth based geometrically frustrated magnets represent a promising new platform for the search of enigmatic quantum spin liquids. Here, the entanglement of spin and orbital...

Skyrmions are chiral spin textures that exist in a variety of magnetic materials. These states are topologically non-trivial, which gives them stability expected to be useful...

Recently there have been many reports on how high-temperature sodium order and dynamics in NaxCoO2 (NCO) can strongly influence both the electronic & magnetic properties at...

Lithium diffusion in magnetic materials is found to be well detected by muon-spin spectroscopy. However, such a diffusive behavior has been measured without potential gradient,...

The research and development of Lead Halide perovskite solar cells is one of the most rapidly growing research areas. Since the discovery of these organic-inorganic metal halide...

Single-Molecular Magnets (SMMs) provide access to the mesoscopic world. They possess slow magnetization relaxation due to an energy barrier induced by axial magnetic anisotropy,...

We plan to investigate by means of zero-field muSR the doping dependence of the sublatticemagnetization in La2Cu1-xZnxO4 and in La2Cu1-xMgxO4. In both systems Cu2+ S=1/2 spins...

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

One of the challenges of developing Silicon-based spintronics technology is developing non-destructive methods for characterizing spin-polarized conduction electrons. Si is...

Having established the photo-MuSR method in intrinsic silicon to investigate excess carrier recombination lifetime and Mu-photocarrier dynamics in our previous experiments, we...

With increasing demands for high performance/capacity rechargeable batteries the materials science community is currently facing two severe issues. First of all there is from a...

We will perform direct laser spectroscopy to measure the ionisation energy of muon defect levels in a semiconductor - specifically silicon carbide. We should see a broad...
