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...

Inducing Room Temperature Ferromagnetism in Phyllosilicates via Iron Implantation

Abstract The modulation of intrinsic two-dimensional (2D) ferromagnetism has attracted significant attention due to its potential applications in spintronics and magnetic field sensing. However, the limited availability of intrinsically magnetic 2D materials has driven the explor...
