Spin Splitter without Spin-Split Bands: A Reconfigurable Altermagnetic Texture
Bin Xi, Jie Lu, Qiang Luo +4
The altermagnetic spin-splitter effect converts an electric field into a transverse pure spin current, with no net magnetization and no charge-Hall counterpart. In established mate…
Beyond-adiabatic flat Chern bands from a double-helix skyrmion crystal
Bin Xi, Ken Chen, Qiang Luo +4
A central challenge in flat-band engineering is suppressing kinetic energy without sacrificing Berry curvature. We show that a double-helix skyrmion crystal (DHSKX)--two sublattice…
Field-selected seven-site topological magnons in a classical frustrated triangular-lattice K-- magnet
Bin Xi, Jie Lu, Shun-Li Yu +1
Defining magnon topology in strongly frustrated magnets is often hindered by the absence of a simple harmonic magnon vacuum at zero field. Within a classical-spin ground-state sear…
Interband optical conductivities in two-dimensional tilted Dirac bands revisited within the tight-binding model
Chao-Yang Tan, Jian-Tong Hou, Xin Chen +6
Within the framework of linear response theory, we theoretically investigated the interband longitudinal optical conductivities (LOCs) in two-dimensional (2D) tilted Dirac bands us…
Fast reversal of Néel vectors in antiferromagnets via domain-wall motion driven by vertically injected spin currents
Jiaxin Du, Mei Li, Bin Xi +4
In this work, we investigate the steady propagation of 180-degree domain walls (180DWs) of Néel vectors in thin antiferromagnetic strips under perpendicularly injected spin current…
Spin-wave Goos-Hänchen effect induced by 360 degree domain walls in magnetic heterostructures
Mei Li, Bin Xi, Yongjun Liu +1
In this work, lateral displacements of transmitted and reflected spin waves at a 360 degree domain wall (360DW), which is referred to as the spin-wave Goos-Hänchen effect (SWGHE),…
Anisotropic magnon-magnon coupling in synthetic antiferromagnets
Wei He, Z. K. Xie, Rui Sun +8
The magnon-magnon coupling in synthetic antiferromagnets advances it as hybrid magnonic systems to explore the quantum information technologies. To induce the magnon-magnon couplin…
