Quantum Anomalous Hall Effect in Oxide Monolayers
Zeyu Li, Xudong Zhu, Yulei Han +1
Quantum anomalous Hall effect (QAHE) arises from the interplay between magnetic order and spin-orbit coupling, which opens up a topologically nontrivial band gap to host chiral edg…
Impact of Thermal Effects on the Current-Tunable Electrical Transport in the Ferrimagnetic Semiconductor MnSiTe
Yiyue Zhang, Xin Jin, ZeYu Li +8
In the ferrimagnetic semiconductor MnSiTe, a colossal magnetoresistance (CMR) is observed only when a magnetic field is applied along the magnetic hard axis ($\mathbf{H…
Chern Number Tunable Quantum Anomalous Hall Effect in Compensated Antiferromagnets
