Surface Originated Cross-Field Anomalous Transport in Magnetoelectric Multilayers
Jin Cao, Wei Du, Xue-Jin Zhang +3
In material systems with slab geometry, the surface contribution to physical responses is commonly expected to diminish rapidly with increasing thickness, giving way to the bulk re…
Nonperturbative Magnetic Orbital Hall Effect in Altermagnets
Xukun Feng, Jin Cao, Lay Kee Ang +3
Recent studies on altermagnets have focused considerable attention on nonrelativistic effects that persist in the absence of spin-orbit coupling (SOC). As a result, the relative im…
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…
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…
Eccentricity valley Hall effect
Jin Cao, Shen Lai, Cong Xiao +2
Valleytronics harnesses the valley degree of freedom -- energy-degenerate extrema in the electronic band structure -- for information storage and processing. Valley Hall effect (VH…
Two-Dimensional Altermagnetic Iron Oxyhalides: Real Chern Topology and Valley-Spin-Lattice Coupling
Yong-Kun Wang, Si Li, Shengyuan A. Yang
Altermagnets, a novel class of collinear magnetic materials, exhibit unique spin-split band structures, yet topological insulating states in intrinsic altermagnetic systems are rar…
