El 28 de noviembre tendremos un seminario impartido por Andreas K. Schmid, del Lawrence Berkeley National Laboratory


Chirality in magnetic materials is fundamentally interesting and holds potential for logic and memory applications. Using spin-polarized low-energy electron microscopy in combination with in-situ multilayer epitaxy, we investigate how chiral spin textures are stabilized as a result of balancing basic magnetic interactions including exchange, anisotropy, and the Dzyaloshinskii-Moriya interaction. We find that by adjusting multilayer structures the domain wall spin-textures can be switched between left-handed, right-handed, cycloidal, helical and mixed domain wall texture. We also discuss an experimental approach to stabilize skyrmions in magnetic multilayers without external magnetic field. These results exemplify the rich physics of chirality associated with interfaces of magnetic materials.
