Cs1-δV2Te2O hosts hidden altermagnetism consisting of spatially alternating altermagnetic layers whose local spin polarizations are verified by spin-resolved ARPES.
Altermagnetic sublattice order imposes momentum-dependent nodes in the superconducting gap for local pairing interactions and favors nonunitary equal-spin triplet superconductivity at large spin splitting.
Cobalt doping converts FeSb2 into a metallic altermagnet with infrared-visible spin-split bands persisting to room temperature.
Multipole analysis of α-MnTe shows that distinct altermagnetic configurations induce spin-momentum locking with different parities and magnetic spin Hall effects with up to 16% angle, enabling identification of order parameters via anisotropy.
