Emergent magnetic nonanalyticity in Dirac altermagnets
Xizhi Fu, Zhenqiao Huang, Fei Yang +3
Symmetry has long provided the organizing principle for understanding how materials respond to external perturbations. Here we show that what is permitted by symmetry need not be w…
Intrinsic anomalous Hall response in the bilayer kagome ferromagnet CoSn
Yuqi Qin, Soumya Sankar, Xingkai Cheng +4
Transition-metal kagome magnets provide a rich platform for investigating the interplay between layer stacking, magnetic order, and band topology. Here, we report the molecular bea…
Discovery of a symmetry-driven electronic cascade in a -wave altermagnet
Zhouyi Yin, Zheng Shi, Shuxuan Zhang +9
Altermagnets host magnetic compensation together with non-relativistic spin-split bands, a coexistence enabled by crystal symmetry. Yet whether and how crystal symmetry organizes c…
Odd spin symmetry and anisotropy switching in p-wave magnet CeNiAsO
Fayuan Zhang, Huaxun Li, Xingkai Cheng +18
Odd-parity magnets, complementary to altermagnets, exhibit unique properties such as high efficiency in charge-spin conversion and compatibility with conventional superconductivity…
Ultrafast Magneto-optical Fingerprints of Altermagnetism in MnTe
