This lecture covers the transition from basic to advanced nanostructures in quantum and nanocomputing, focusing on domain-magnet logic, skyrmions, and spin waves. It discusses the challenges of clock zones organization, the use of domain walls for interconnects, and the impact of perpendicular magnetic anisotropy. The fabrication process of Co/Pt multilayers is explained, along with the effects of FIB irradiation on intermixing and anisotropy reduction. The lecture also addresses artificial nucleation centers and their role in creating domain walls, as well as the implications of field-induced intermixing on magnetocrystalline anisotropy.
