Defect Geometry Selects Polar and Anomalous Hall Phases in Two-Dimensional Altermagnets
Point defects in altermagnets can create phases absent in the pristine host by selectively breaking crystal symmetries.
Point defects in altermagnets can create phases absent in the pristine host by selectively breaking crystal symmetries. Combining symmetry analysis, first-principles calculations, and Hamiltonian modeling, we identify how point impurities modify the altermagnetic phase. Using…
