Observation of hidden altermagnetism in CsVTeO
Guowei Yang, Ruihan Chen, Changchao Liu +25
Altermagnets are characterized by anisotropic band/spin splittings in momentum space, dictated by their spin-space group symmetries. However, the real-space modulations of altermag…
Large ferromagnetic-like band splitting in ultrathin films
Hao Zheng, Yifu Xu, Guowei Yang +9
Two-dimensional (2D) magnetic materials provide a unique platform for exploring quantum phases from magnetic order in reduced dimensions. While there have been extensive studies on…
flat bands and coupled moments in the kagome-honeycomb permanent magnet SmCo
Hao Zheng, Zhiguang Xiao, Ze Pan +19
Rare earth permanent magnets (REPMs) with both localized moments and itinerant conduction bands are not only important for fundamental research but also have significant technologi…
Orientation-dependent superconductivity and electronic structure of the rare-earth metal/KTaO3 interfaces
Guowei Yang, Weifan Zhu, Jiawen Zhang +10
The recent discovery of orientation-dependent superconductivity in KTaO3-based interfaces has attracted considerable interest, while the underlying origin remains an open question.…
Three-dimensional mapping of the altermagnetic spin splitting in CrSb
Guowei Yang, Zhanghuan Li, Sai Yang +20
Altermagnetism, a kind of collinear magnetism that is characterized by a momentum-dependent band and spin splitting without net magnetization, has recently attracted considerable i…
