Interlayer Dzyaloshinskii–Moriya Interaction in Synthetic Ferrimagnets for Spiking Neural Networks

open access: yesAdvanced Science, EarlyView.
This work introduces a groundbreaking integration of asymmetric magnetic structures (synthetic ferrimagnets) and antisymmetric magnetic interaction (interlayer Dzyaloshinskii–Moriya interaction) for the first time. It addresses the critical challenge of IL‐DMI detection and shows the discovery of unprecedented analog‐like spin‐orbit torque switching ...

Room‐Temperature Magnetic Skyrmions and Intrinsic Anomalous Hall Effect in a Nodal‐Line Kagomé Ferromagnet MnRhP

open access: yesAdvanced 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 ...

Spectroscopic Evidence of Edge‐Localized States in an Antiferromagnet Topological Insulator NdBi

open access: yesAdvanced Science, EarlyView.
Using spin‐polarized scanning tunneling microscopy (STM) in conjunction with quasiparticle interference, we successfully identify distinct signatures of the ferromagnetic and antiferromagnetic terminations in NdBi, a rare‐earth monopnictide exhibiting non‐trivial topology and magnetism. We demonstrate that step edges on ferromagnetic surfaces host well‐

Large Room Temperature Anomalous Nernst Effect Coupled with Topological Nernst Effect from Incommensurate Spin Structure in a Kagome Antiferromagnet

open access: yesAdvanced 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 ...

Emerging of Anomalous Higher‐Order Topological Phases in Altermagnet/Topological Insulator Heterostructure by Floquet Engineering

open access: yesAdvanced Science, EarlyView.
We combine altermagnet with topological insulators and subject the structure to Floquet driving. This breaks time‐reversal symmetry and creates a new type of higher‐order topological insulator. Its key feature is the emergence of programmable “0/π‐corner modes” that can be controlled by magnetic field direction, offering a novel dynamic platform for ...

Enhanced Photocatalytic CO2 Reduction Performance by External Electric Field‐Driven Charge Separation on Interdigitated Micro‐Spacing Structure

open access: yesAdvanced Science, EarlyView.
An external electric field‐enhanced photocatalytic system is developed using interdigitated electrodes with 100 µm spacing to overcome the liquid‐phase limitations of traditional PEC. The induced high‐intensity electric field effectively drives the directional migration of charge carriers under low voltage. This strategy significantly suppresses charge
