We propose to study polarised neutron reflectivity from a GdCo/Si/Co/Si multilayers. Magnetic rare earth/transition metal (RE/TM) multilayers have been subject of considerable...

Building on our preliminary neutron transmission results from the CRISP instrument (see below), we propose to undertake a detailed study of critical fluctuations in 3He near its...

We propose to study off-specular polarised neutron reflectivity from an array of CoFeB nanostructures. Many groups use Permalloy to form these types of nanostructures, however,...

A large magnetoresistance (TMR) is expected when half metallic ferromagnets are used in magnetic tunneling junctions with polycrystalline AlOx barrier. We have recently observed...

Recently, we have demonstrated that a large ferromagnetic moment can be induced at theinsulating barrier (La0.3Ca0.7MnO3 (LC7MO)) separating two...

Reflectometry is a technique that is capable of vector magnetometry. By selecting the appropriate valves of Q we could access the different forms of magnetic disorder, either...

One of the current challenges in solid state physics is the observation and ultimately control of the Majorana excitations sometimes called Majorana fermions. Devices based on...

In our recent experiment RB1120146 we have obtained new exciting results on neutron scattering on liquid He surface. At 1.5 and 2.3K there was no difference in reflectivity...

Magnetic rare earth/transition metal (RE/TM) multilayers have been a subject of considerableinterest in recent years, given the antiferromagnetic exchange coupling between RE...

FeSi is a member of the transition metal (TM) monosilicides. The crystal structure is isostructural from MnSi through to CoSi with magnetic properties that alter dramatically...

To continue with our study on the interaction between superconducting (SC) and ferromagnetic (FM) order parameters we propose to study, by means of Polarized Neutron...

The spin Seebeck effect is a newly discovered phenomenon that if harnessed, could result in a significant improvement of the efficiency of thermoelectric energy generators. In...

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,...

More than four decades ago A. F. Andreev predicted theoretically the existence of quantum statesof 3He atoms on free surface of liquid 4He . In other words, at low temperatures,...

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...

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

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...

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...

In our previous experiments we have investigated the surface properties of liquid 3He - 4He mixtures by neutron reflection. We have shown that in broad temperature range there...

Proximity effects associated with magnetic impurities embedded in paramagnetic Pd have been known to produced so-called giant moments. It has been demonstrated that confining Fe...
