Field‐Free Spin–Orbit Torque Switching of Perpendicular Magnetization by PtTe2/WTe2 Bilayers at Sub‐ns Timescales

Advanced Functional Materials, EarlyView.
This work demonstrates ultrafast, field‐free spin–orbit torque (SOT) switching using a PtTe2/WTe2/CoFeB multilayer, achieving sub‐nanosecond magnetization reversal with record‐low energy consumption. The PtTe2/WTe2 bilayer generates an intrinsic out‐of‐plane spin current, enabling deterministic switching without external fields.

Hollow‐Structured Nanorobot with Excellent Magnetic Propulsion for Catalytic Pollutant Degradation, Anti‐Bacterial and Biofilm Removal

Advanced Healthcare Materials, EarlyView.
A hollow‐structured Fe3O4@AgAu@PDA‐ZnPc nanosphere has been developed, exhibiting controllable catalytic activity and “photothermal‐photodynamic‐Ag+” coupling antibacterial characteristics. When subjected to a rotating magnetic field, these performances are uniquely enhanced by magnetic propulsion, allowing the nanosphere to function as a magnetic ...

Microscopic origin of the optical processes in blue sapphire [PDF]

, 2013
Al2O3 changes from transparent to a range of intense colours depending on the chemical impurities present. In blue sapphire, Fe and Ti are incorporated; however, the chemical process that gives rise to the colour has long been debated.
