Accurate, safe and cheap hydrogen detectors functioning under a wide range of conditions are a vital ingredient for using hydrogen as an energy carrier. A novel, safe and cheap...

The redox driven swelling and deswelling of conducting polymers has been termed Electronic Muscle actuation. One application of this property is as a sphincter-like valve in a...

Superconductivity and ferromagnetism are perhaps the best examples of how quantum mechanics can be employed to explain macroscopic phenomena. The two states, both containing...

The use of deuteration to overcome the difficulties associated with the incoherent scattering from hydrogen, is a well established technique. However, there are increasing...

The spin Seebeck effect is able to convert a temperature gradient into a spin current. Many potential applications exist for the field of spintronics, which use these spin...

This experiment seeks to characterise the monolayer composition and structure of binary mixtures of fatty acid and amine. This represents a key additive system used commercially...

Today, a number of technological devices, such as the readout sensor in the hard disc drive, have used the exchange bias (EB) effect, which arises in a...

Magnetic HEA thin films could open up the possibility to develop spintronic devices for use in hostile environments e.g. for high temperature applications. Previous studies have...

The tunnel magnetoresistive effect (TMR) is critically dependent upon interfacial disorder. Polarised neutron reflectivity will be used to characterise the magnetic roughness at...

Ferrofluids are liquids having magnetic nanoparticles dispersed in a solvent and covered with surfactants to prevent them from agglomeration. The particles can form smectic like...

There is currently tremendous interest in unconventional superconductors where p-wave, d-wave or f-wave angular momentum states exist. The existence of p or f-wave odd symmetry...

Six days of OFFSPEC beam time is requested to expand our recent investigations of emergent magnetisation dynamics in ensembles of interconnected ring-shaped nanowires. In recent...

For many Heusler compounds a spin polarisation close to 100% was predicted by band structure calculations. Thus if those materials are incorporated in magnetic tunnel junctions,...

Multiferroic systems have more than one functionality, i.e. ferromagnetism, ferroelectricity, ferroelasticity and ferrotoroidicity. In nature there are few materials that...

We wish to investigate the magnetic structure of a series of magnetic multilayers using a new technique we have successfully implemented called Spin Echo Modulated Small Angle...

We have recently performed a `proof-of-principle' Low Energy Muon Spin Rotation experiment on an organic spin valve. In an extension to our muon measurements and an attempt to...

Morphological features of plant waxes vary from species to species, but little is understood about what controls these morphological changes although it is widely believed that...

In this work we will investigate how the magnetic properties of nanometer thick iron-oxide films can be manipulated by heating them in air. Our preliminary results indicate that...

Hydrogels are water-rich polymer networks made from natural or synthetic polymers, which are widely used in biomaterials, medicine and antifouling. We have developed PEG-based...

The spin Seebeck effect generates spin currents in various materials when they are subjected to a temperature gradient. These spin currents persist over length scales many...
