Spin-orbit torque at surfaces and interfaces  

The phenomenon of the spin-orbit torque (SOT) is attracting increasing attention both in the fields of theoretical as well as applied spintronics. The principle of SOT relies on the spin-orbit interaction in combination with ferromagnetic magnetization and broken inversion symmetry, and it can be used to successfully switch the magnetization of a deposited collinear ferromagnetic layer with strong perpendicular anisotropy in an in-plane current geometry [2]. SOT becomes a candidate for non-volatile random access and cache memories owing to the possibility of ultrafast switching [4].

Despite already being a valid candidate for revolutionalizing spintronics, the origins of SOT on the microscopic and material specific level are still very poorly understood and intensely debated. In addition to purely interfacial effects, the spin-current generation inside the non-magnetic layer is believed to be the main source of large SOTs in generic systems [2,3]. The purpose of the suggested focus session is to bring the attention of the wider physics community in Germany to this promising direction in spintronics.
