Symmetry-Driven Electrical Switching of Anisotropic Skyrmion Hall Effect in Altermagnets
Wenhui Du, Kaiying Dou, Ying Dai +3
Controlling the skyrmion Hall effect (SkHE) is pivotal for developing topological spintronics but typically relies on magnetic field reversal. Here, we demonstrate a general strate…
Design of Skyrmion Bags with Tunable Topology in Symmetry-Broken 2D Lattices
Junhuang Yang, Kaiying Dou, Ying Dai +2
Magnetic skyrmion bags, as high-order topological swirling spin textures, offer rich fundamental physics and distinct advantages for spintronic applications; however, their realiza…
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…
