Zero-net-magnetization hybrid magnet
San-Dong Guo, Shi-Hao Zhang
Zero-net-magnetization magnets possess ultradense and ultrafast application potential, benefiting from their intrinsic zero stray field and terahertz dynamics characteristics. Here…
Hidden fully-compensated ferrimagnetism
San-Dong Guo
Incorporating zero-net-magnetization magnets that exhibit spin-splitting into spintronics delivers key advantages: faster switching dynamics, greater immunity to destabilizing fiel…
Spin ordering-induced fully-compensated ferrimagnetism
San-Dong Guo, Shaobo Chen, Guangzhao Wang
Fully-compensated ferrimagnets exhibit zero net magnetic moment yet display non-relativistic global spin splitting, making them highly advantageous for constructing high-performanc…
Weak valley-layer coupling and valley polarization in centrosymmetric monolayer
San-Dong Guo, Liguo Zhang, Xiao-Shu Guo +1
Using the valley degree of freedom as a carrier of information for storage and processing, valley polarization plays a crucial role. A variety of mechanisms for valley polarization…
Symmetry-breaking induced transition among net-zero-magnetization magnets
San-Dong Guo, Xiao-Shu Guo, Guangzhao Wang
Net-zero-magnetization magnets have garnered intensive research attention due to their ultradense and ultrafast potential. In terms of the symmetric classification of connecting ma…
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…
