Symplectic connection third-order Hall effect in a room-temperature ferromagnet
Yu Cao, Xukun Feng, Yiming Guo +18
Third-order nonlinear Hall effects (THE) have recently attracted considerable experimental interest as powerful probes for quantum geometric properties in emergent quantum material…
Giant Room-Temperature Third-Order Electrical Transport in a Thin-Film Altermagnet Candidate
Hongyu Chen, Peixin Qin, Ziang Meng +14
Quantum geometry, a quantum mechanical quantity comprised of Berry curvature and quantum metric, describes the geometric structure of the electronic bands in solids. The correlatio…
Nonlinear Magnetic Orbital Hall Effect Induced by Spin-Orbit Coupling
Hui Wang, Huiying Liu, Yanfeng Ge +6
Electrical readout of 180 switching in strictly compensated collinear antiferromagnets remains a major challenge in antiferromagnetic spintronics. Electrical writing of per…
Out-of-Plane Nonlinear Orbital Hall Torque
Hui Wang, Xukun Feng, Jin Cao +5
Despite recent advances in orbitronics, generating out-of-plane orbital torques essential for field-free deterministic switching of perpendicular magnetization remains a key challe…
Nonlinear Néel Spin-Orbit Torque in Centrosymmetric Antiferromagnets
Jin Cao, Weikang Wu, Huiying Liu +4
Electric control of Néel vector is a central task of antiferromagnetic (AFM) spintronics. The major scheme so far relies on the linear Néel torque, which however is restricted to…
