The Motif Symmetry-Breaking Index turns binary altermagnet symmetry classification into a continuous, DFT-free design variable, enabling machine-learning discovery of candidates with spin-splitting energies up to 1.3 eV.
DFT calculations find stronger effective valence-band spin splitting in (R/S-NEA)PbI3 than in (R/S-PEA)PbI3 due to larger SOC gaps and band crossings, with opposite spin textures for the two compounds matching their opposite octahedral distortions.
