Potassium tetracyanoquinodimenthane (KTCNQ) undergoes a spin-Peierls (SP) transition at 396K where a transformation from uniform to dimerised TCNQ- molecules in 1D columns...

Magnetic cooling promises efficiency savings at room temperature but requires rapid cycling of a magnetic refrigerant in a magnetic field. Refrigerants with first order...

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...

The reversible interconversion of protons and dihydrogen is an electrochemical process of fundamental importance to a hydrogen economy. The process requires catalysis to proceed...

PffBT4T-2OD is one of the most recent and most successful low bandgap conjugated polymers used in organic photovoltaics - PffBT4T-2OD based OPV devices have power conversion...

Nearly all polymers form glasses and the glass transition at temperature Tg dominates many physical properties of polymers that are relevant for their applications. The most...

We propose a series of measurements to complete the previous direct spectroscopic measurements of the Muonium defect energy levels in Silicon Carbide (SiC; RB110134). We will...

Topological insulators (TIs) are of inherent interest as they are conducting on the surface whilst insulating on the bulk. We would like to investigate magnetically doped...

The emerging field of organic spintronics is especially promising for new technologies, owing to the long spin coherence times, large flexibility and low production costs of the...

The quantum spin liquid (QSL) state is one of the possible outcomes of quantum fluctuations advancing magnetic systems into a disordered phase. After more than 30 years of quest...

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...

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...

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...

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...

A grand challenge facing society today is the need to develop green energy technologies. For instance, as we increase our use of renewable energy sources to cut our consumption...

The overall aims of our project is to advance the performance of NIBs in terms of energy and power density by creating a closed-loop approach for materials design,...

One of the technological goals is to create materials that show high permittivity and low dielectric loss, which has been achieved by the co-doping of Nb and In into rutile...
