Spintronics is a rapidly growing research field within academia and industry, where the behaviour of the electron spin is used to create new electronic devices with many advantages over their charge-based counterparts (for instance non-volatile memory with low power consumption). In solid state materials, because of the strong electric fields that exist due to the nuclei, relativistic spin-based effects (generally termed as the spin-orbit interaction) naturally appear in the electronic structure and transport phenomena. Strongly spin-orbit coupled materials are a fascinating physical playground within which novel spin transport properties can be found and research in this area has many avenues still to explore.
Using state-of-the-art spin excitation and detection systems built in the London Centre for Nanotechnology, we have various methods to probe materials’ spin-orbit properties in a variety of experimental conditions. For instance, we can use microwave currents to excite GHz spin dynamics through the spin-orbit interaction, or the spin-Hall effect can be probed through optical spin orientation techniques.
This 4th-year project will focus on exploring spin-orbit phenomena in solid state materials. It will also benefit from the afore-mentioned existing facilities as well as from senior group members who are willing to support this project.
