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…
Non-altermagnetic spin texture in MnTe
Meng Zeng, Pengfei Liu, Ming-Yuan Zhu +19
Recently, altermagnets have emerged as promising candidates in spintronics, uniquely combining large spin-polarized electronic states with zero net magnetization. A prominent examp…
Topological Charge Quadrupole Protected by Spin-Orbit U(1) Quasi-Symmetry in Antiferromagnet NdBiPt
Ao Zhang, Xiaobing Chen, Jiayu Li +3
The interplay of symmetry and topology in crystal solids has given rise to various elementary excitations as quasiparticles. Among these, those with significant Berry-phase-related…
Observation of Spin Splitting in Room-Temperature Metallic Antiferromagnet CrSb

Unconventional spin textures emerging from a universal symmetry theory of spin-momentum locking
Yuntian Liu, Jiayu Li, Pengfei Liu +1
Spin textures, i.e., the distribution of spin polarization vectors in reciprocal space, exhibit diverse patterns determined by symmetry constraints, resulting in a variety of spint…
Observation of plaid-like spin splitting in a noncoplanar antiferromagnet
Yu-Peng Zhu, Xiaobing Chen, Xiang-Rui Liu +27
Spatial, momentum and energy separation of electronic spins in condensed matter systems guides the development of novel devices where spin-polarized current is generated and manipu…
Chiral Dirac fermion in a collinear antiferromagnet
Ao Zhang, Ke Deng, Jieming Sheng +18
In a Dirac semimetal, the massless Dirac fermion has zero chirality, leading to surface states connected adiabatically to a topologically trivial surface state as well as vanishing…
Fragile Symmetry-Protected Half Metallicity in Two-Dimensional van der Waals Magnets: A Case Study of Monolayer FeCl2
Qiushi Yao, Jiayu Li, Qihang Liu
Two-dimensional (2D) half-metallic materials are of great interest for their promising applications in spintronics. Although numerous of 2D half-metals have been proposed theoretic…
Spin-group symmetry in magnetic materials with negligible spin-orbit coupling

Accurate polymorphous description of the paramagnetic phases in MnBiTe
Yufei Zhao, Qiushi Yao, Pengfei Liu +1
Temperature-driven phase transition is a long-standing frontier in material science, among which the most common phenomenon is the transition from a low-temperature magnetic-ordere…
Symmetry-assisted protection and compensation of hidden spin polarization in centrosymmetric systems
Yingjie Zhang, Pengfei Liu, Hongyi Sun +2
It is recently noted that in certain centrosymmetric compounds, spin-orbit interaction couples each local sector that lacks inversion symmetry and thus leads to visible spin polari…
