Imaging the ultrafast coherent control of a skyrmion crystal
Phoebe Tengdin, Benoit Truc, Alexey Sapozhnik +14
Exotic magnetic textures emerging from the subtle interplay between thermodynamic and topological fluctuation have attracted intense interest due to their potential applications in…
Gate-tunable Intrinsic Anomalous Hall Effect in Epitaxial MnBi2Te4 Films
Shanshan Liu, Jiexiang Yu, Enze Zhang +11
Anomalous Hall effect (AHE) is an important transport signature revealing topological properties of magnetic materials and their spin textures. Recently, antiferromagnetic MnBi2Te4…
Electrical manipulation of skyrmions in a chiral magnet
Weiwei Wang, Dongsheng Song, Wensen Wei +6
Writing, erasing and computing are three fundamental operations required by any working electronic devices. Magnetic skyrmions could be basic bits in promising in emerging topologi…
Magnetic Skyrmion Bundles and Their Current-Driven Dynamics
Jin Tang, Yaodong Wu, Weiwei Wang +6
Quantization of topological charges determines the various topological spin textures that are expected to play a key role in future spintronic devices. While the magnetic skyrmion…
Discrete Quantum Geometry and Intrinsic Spin Hall Effect
Jie-Xiang Yu, Jiadong Zang, Roger K. Lake +2
We show that the quantum geometry of the Fermi surface can be numerically described by a 3-dimensional discrete quantum manifold. This approach not only avoids singularities in the…
Electronic scattering off a magnetic hopfion
Sergey S. Pershoguba, Domenico Andreoli, Jiadong Zang
We study scattering of itinerant electrons off a magnetic hopfion in a three-dimensional metallic magnet described by a magnetization vector . A hopfion is a…
