Starting from thin film elaboration and device patterning, we fabricate and study novel devices by employing materials with tailored interface functionalities. Spin-orbitronics is an emerging field of spintronics, concerning the use of spin-orbit coupling (SOC) in magnetic and nonmagnetic materials to generate, detect and exploit spin-polarized currents. SOC in magnetic multilayer stacks lacking inversion symmetry promotes, via the interfacial Dzyalosinskii-Moriya interaction, chiral spin textures, like chiral domain walls or skyrmions, that can be efficiently manipulated by the spin currents. This opens the way for a new generation of energy-efficient electrically controlled spintronic devices, a key challenge for modern electronics.
