Alternative to the classical spintronics, the new research directions of spin-orbitronics concerns the use of spin-orbit coupling (SOC) in nonmagnetic materials to generate, detect or exploit spin-polarized currents. This opens the way to control spintronic devices without the use of magnetic fields through the current induced spin-orbit torques (SOTs). Moreover, SOC in magnetic multilayer stacks lacking inversion symmetry promotes, via the interfacial Dzyalosinskii-Moriya interaction (IDMI), chiral spin textures, like skyrminons, that can be efficiently driven SOTs.

   

The spin-orbitronics research direction of C4S is coordinated by M. Gabor
