Altermagnets exhibit a resonant third-order intrinsic anomalous Hall effect from the Berry curvature quadrupole, serving as a quantum geometric transport fingerprint.
Antiferromagnetic skyrmions exhibit bidirectional motion under current-induced torques above a threshold due to competing effective forces, enabling logic gates.
Cr doping of FeSb2 breaks time-reversal symmetry with bulk short-range spin-compensated order below ~3.5 K but does not stabilize long-range collinear altermagnetic order.
Ferromagnetic Ni contacts enable anomalous and nonlinear Hall effects in centrosymmetric CrSb, with Hall-slope sign inversion and bow-tie hysteresis attributed to bulk altermagnetism plus topological surface states.
Symmetry-guided graph neural networks trained on 200 structures screen 100,000+ iTMD configurations to identify 55 antiferromagnetic spintronics candidates with d-wave altermagnetism or giant T-odd spin Edelstein effects.
