A direct measurement of the spin accumulation in a magnetic nanostructure is a key requirement to the theoretical and ultimately technological exploitation of picosecond...

Neutron reflectometry (NR) is a very powerful technique for the study of thin layers. It is able to measure composition, thickness and roughness and is a very penetrating...

The influence of surfaces and interfaces on the dynamical properties of polymers has been a very active area in recent years. The recently developed low energy muon (LEM)...

The breaking of time-reversal symmetry via ferromagnetic (FM) doping is crucial for enabling many interesting phenomena in topological insulators (TIs) such as the Quantum...

Ferromagnetic III-V semiconductors lie at the confluence of magnetic storage and optoelectronic technologies, allowing the development of semiconductor heterostructure devices...

FeRh in the CsCl structure is an interesting material with a tunable magnetostructural phase transition close to, or just above room temperature. On heating through the...

Magnetic structures with an out of plane magnetic moment can be found in the latest generation hard disk drive. Interactions between a material with controllable out of plane...

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

We ask for 8 days of beam time on CRISP to study the absorption and desorption of hydrogen and deuterium in Ti/Mg/Pd trilayer samples. Our specific objective is to understand in...

FeRh exhibits a fascinating structural and magnetic transition from room temperature antiferromagnetism to ferromagnetism at higher temperatures. This complex transition is...

Nanocarbon materials such as C60 show fascinating transport properties when in contact with a ferromagnet. Previous results indicate that this could be due to a spin polarized...

We intend to explore the intermediate q-range (0.1 to 50\AA-1) in nanogranular Fe35Ag65 and Fe15Ag85 thin films. These systems have been proven to have a crossover between a...

We intend the measure the neutron reflectivity of a purely magnetic interface generated at a ferromagnetic/antiferromagnet phase boundary within an FeRh epilayer, a material...

The exchange biasing effect in the thin film IrMn3/Fe depends strongly on the degree of structural ordering of the underling antiferromagnetic IrMn3 pinning layer. In this work...

Nanogranular thin films of FexM100-x (M=Au,Ag; x=7,20,39) are an excellent system to study the magnetism of nanoparticles in diamagnetic matrices coupled by direct, RKKY and...

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,...

The realisation of room temperature magnetic semiconductors would be a significant milestone on the route to the next generation of spintronic materials. Raising the ordering...

In addition to smoothing and self-affine roughening ion bombardment of solid surfaces can result in ripple and dot structures with nanometer scale dimensions. This method...
