Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Counterion‐Controlled Photocatalytic Doping of Organic Semiconductors

Advanced Materials, EarlyView.
Counterion size is shown to actively control photocatalytic doping in organic semiconductors. Small anions suppress aggregation of acridinium photocatalysts, enhance electron transfer, and dramatically increase doping efficiency. This simple strategy enables conductivities up to 2000 S cm−1 in benchmark polymers, revealing counterions as a powerful yet

Microwave Absorption for Detection of Dirac Fermions in SnTe Films

Advanced Materials Interfaces, EarlyView.
Microwave absorption can detect Dirac fermions in samples exposed to the atmosphere. Results showed that although topological surface states are robust against environmental degradation, they are not detectable by electrical transport measurements. Hence, microwave absorption can detect Dirac fermions even in samples whose surfaces have deteriorated ...

Exploring the Potential of Microwave Annealing for Enhancing Si‐based GeSn Lasers

Advanced Materials Technologies, EarlyView.
We explore low‐thermal‐budget microwave annealing to enhance the performance of group‐IV GeSn lasers on Si. Microwave annealing under optimal conditions can simultaneously relax unwanted compressive strain and enhance the material quality of the GeSn active layer, thereby reducing the threshold and increasing the laser operating temperature.
