Focused He⁺ Ion Irradiation for Deterministic Nanoscale Domain Wall Pinning and Domain Nucleation in Current-Driven Magnetization Switching

Abstract Predictive domain wall nucleation, propagation, and pinning is achieved by He⁺ ion irradiation of spin-orbit torque thin film devices. Engineering the magnetic anisotropy landscape with nm precision, we demonstrate that non-irradiated gaps as small as 10 nm can act as re...
