Heterostructures consisting of magnetic insulator layers (e.g., EuS, YIG) and topological insulator films have also been explored for realizing QAH insulators. The proximity-induced magnetic exchange ...

Beijing Zhongke Journal Publising Co. Ltd. Magnetic chiral DWs are a class of topological structures with discrete symmetries. As the boundary between domains with opposite magnetization, this ...

The quantum anomalous Hall effect (QAHE) has unique advantages in topotronic applications, but it is still a key scientific challenge to realize the QAHE with tunable magnetic and topological ...

Researchers at the University of Würzburg have developed a method that can improve the performance of quantum resistance standards. It's based on a quantum phenomenon called Quantum Anomalous Hall ...

Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In their experiment, photons drift sideways in perfectly defined, quantized steps ...
