Ultrafast laser driven ferromagnetic-antiferromagnetic skyrmion switching in 2D topological magnet
Kaiying Dou, Wenhui Du, Zhonglin He +3
Light-spin coupling is an attractive phenomenon from the standpoints of fundamental physics and device applications, and has spurred rapid development recently. Whereas the current…
Gate-Controllable Quadri-Layertronics in 2D Multiferroic Antiferromagnet
Ting Zhang, Mingsheng Wang, Xilong Xu +2
Layertronics that manifests layer Hall effect is typically considered to intrinsically possess binary physics. Using symmetry arguments and a low-energy kp model, we show that the…
Ferro-Valleytricity with In-Plane Magnetization
Yibo Liu, Yangyang Feng, Ying Dai +2
Ferro-valleytricity, a fundamental phenomenon that manifests spontaneous valley polarization, is generally considered to occur in two-dimensional (2D) materials with out-of-plane m…
Coupling multi-space topologies in 2D ferromagnetic lattice
Zhonglin He, Wenhui Du, Kaiying Dou +3
Topology can manifest topological magnetism (e.g., skyrmion and bimeron) in real space and quantum anomalous Hall (QAH) state in momentum space, which have changed the modern conce…
Ferroelectrovalley in Two-Dimensional Multiferroic Lattices
Jiangyu Zhao, Yangyang Feng, Ying Dai +2
Engineering valley index is essential and highly sought for valley physics, but currently it is exclusively based on the paradigm of the challenging ferrovalley with spin-orientati…
