Hidden altermagnetism
San-Dong Guo
Hidden spin polarization (HSP) with zero net spin polarization in total but non-zero local spin polarization has been proposed in certain nonmagnetic centrosymmetric compounds, whe…
Multifield tunable valley splitting and anomalous valley Hall effect in two-dimensional antiferromagnetic MnBr
Yiding Wang, Hanbo Sun, Chao Wu +4
Compared to the ferromagnetic materials that realize the anomalous valley Hall effect by breaking time-reversal symmetry and spin-orbit coupling, the antiferromagnetic materials wi…
Proposal of a general scheme: valley polarization in antiferromagnetic bilayer systems
San-Dong Guo, Ping Li, Guangzhao Wang
Superior to ferromagnetic (FM) valleytronics, antiferromagnetic (AFM) counterpart exhibits ultradense and ultrafast potential due to their intrinsic advantages of zero stray field,…
Valley polarization in 2D tetragonal altermagnetism
San-Dong Guo Xiao-Shu Guo, Guangzhao Wang
The altermagnetism caused by alternating crystal environment provides a unique opportunity for designing new type of valley polarization. Here, we propose a way to realize valley p…
Valley polarization in twisted altermagnetism
San-Dong Guo, Yichen Liu, Cheng-Cheng Liu
The combination of altermagnetism, twistronics and valleytronics is of great significance for potential applications in advanced electronic devices. Twisted magnetic van der Waals…
