Nonvolatile Electrical Control of Spin via Sliding Fractional Quantum Multiferroics
Jiajun Lu, Mu Tian, Chaoxi Cui +3
We propose a fractionally quantized polarization induced by interlayer sliding in bilayer altermagnets, unveiling a previously unrecognized multiferroic phase termed sliding fracti…
Switchable Giant Spin Injection Current in Janus Altermagnet FeSSeO
Fanxian Pei, Run-Wu Zhang, Lei Li +2
Generating and controlling spin current in miniaturized magnetic quantum devices remains a central objective of spintronics, due to its potential to enable future energy-efficient…
Sliding Ferroelectrics Induced Hybrid-Order Topological Phase Transitions
Ning-Jing Yang, Jian-Min Zhang, Xiao-Ping Li +4
We propose ferroelectric layer sliding as a new approach to realize and manipulate topological quantum states in two-dimensional (2D) bilayer magnetic van der Waals materials. We s…
Quantized Spin-Hall Conductivity in Altermagnet FeTeO with Mirror-Spin Coupling
Run-Wu Zhang, Chaoxi Cui, Yang Wang +3
Due to spin-orbit coupling (SOC), crucial for the quantum spin Hall (QSH) effect, a quantized spin-Hall conductivity has not yet been reported in QSH insulators and other realistic…
Essentially degenerate hidden nodal lines in two-dimensional magnetic layer groups
Xiao-Ping Li, Chaoxi Cui, Lei Wang +4
According to the theory of group representations, the types of band degeneracy can be divided into accidental degeneracy and essential degeneracy. The essentially degenerate nodal…
