Advanced Science, EarlyView.MnRhP has been identified as a novel kagomé magnet that hosts magnetic skyrmions above room temperature and exhibits a large intrinsic anomalous Hall effect. The latter originates from Berry curvature associated with gapped nodal lines, establishing MnRhP as a promising platform for exploring high‐temperature topological phenomena in both real and ...

Strain‐Assembled Crystalline SrRuO3 Microtube and Emergent Curvilinear Magnetism
Advanced Science, EarlyView.The interfacial‐strain assembly based on planar nanomembranes presents a promising approach for constructing novel magnetic microstructures. By employing the perpendicular magnetic anisotropic SrRuO3 freestanding nanomembrane as a model system, we exploit the interfacial strain effect within the crystalline SrTiO3/SrRuO3 bilayer, and successfully ...

Advanced Science, EarlyView.This study demonstrates that ErMn₆Sn₆, a kagome antiferromagnet hosting incommensurate spin textures, sustains finite scalar spin chirality that drives topological states. The anomalous Nernst effect (ANE) originates from the strong Berry curvature of Chern‐gapped Dirac fermions, while the topological Nernst effect (TNE) arises from emergent fields ...

Magnetic bilayer-skyrmions without skyrmion Hall effect
Nature Communications, 2016 AbstractMagnetic skyrmions might be used as information carriers in future advanced memories, logic gates and computing devices. However, there exists an obstacle known as the skyrmion Hall effect (SkHE), that is, the skyrmion trajectories bend away from the driving current direction due to the Magnus force.

Device‐Level Implementation of Reservoir Computing With Memristors
Advanced Intelligent Systems, EarlyView.Reservoir computing (RC) is an emerging computing scheme that employs a reservoir and a single readout layer, which can be actualized in the nanoscale with memristors. As a comprehensive overview, the principles of RC and the switching mechanisms of memristors are discussed, followed by actual demonstrations of memristor‐based RC and the remaining ...

Gravitating BPS Skyrmions [PDF]
Journal of High Energy Physics, 2015 The BPS Skyrme model has many exact analytic solutions in flat space. We generalize the model to a curved space or spacetime and find that the solutions can only be BPS for a constant time-time component of the metric tensor. We find exact solutions on the curved spaces: a 3-sphere and a 3-hyperboloid; and we further find an analytic gravitating ...
