Topological Transport Effects and Pure Spin Currents in Nanostructures
… The first part of this work is focused on the magnetoresistance observed in spin Hall active metals in contact with a magnetic insulator. In such bilayers, the interfacial spin accumulation caused by the spin Hall effect in the metal can interact with the magnetic insulator, giving rise to …

Tuning Spin Currents with Ultrathin Heavy Metal Microstructure
All-metallic spintronic heterostructures have the ability to generate pure spin currents at low resistance-area products via spin-orbit coupling. Heavy metal/ferromagnet (HM/NM) bilayers are often used in this context to extract key spin-dependent parameters such as the spin Hall angle, 𝜃, and spin …

Realisation of De Gennes’ Absolute Superconducting Switch and Magnetic Exchange Field Effects at Metallic and Superconductor Interfaces
… and metallic thin-films exhibiting spin-orbit coupling. Firstly, we demonstrate an absolute superconducting switch, confirming a prediction by Pierre-Gilles de Gennes in 1966. This is achieved using a thin-film multilayer of EuS/Au/Nb/EuS, where Au is a metal with strong spin-orbit …

Probing the Behaviour of Antiferromagnets: Electric and Magnetic Measurements Across a Range of Length-scales
The spin Hall effect (SHE) describes the generation of a spin current orthogonal to an applied charge current within a heavy metal, whilst the spin Seebeck effect (SSE) refers to the generation of a spin current due to thermal gradients within a magnetic material. Both effects have attracted …
