Altermagnets exhibit a resonant third-order intrinsic anomalous Hall effect from the Berry curvature quadrupole, serving as a quantum geometric transport fingerprint.
In [(R)/(S)-MPA]2[MnCl4(H2O)], first-principles calculations and spin-space-group analysis predict altermagnetic spin splitting whose sign and momentum pattern are controlled by the coupled chiral, polar, and magnetic degrees of freedom, yielding explicit sign rules for electronic and magneto-optica
In a 2D model Hamiltonian, orbital Hall conductivity quantizes when altermagnetism exceeds sp-hybridization while spin Hall quantizes when Rashba SOC is weaker, with both independent of the other coupling and arising from Fermi-surface Berry curvature.

Quantized orbital and spin Hall transport: interplay between $sp$-hybridization, altermagnetism and spin-orbit coupling
In a 2D model Hamiltonian, orbital Hall conductivity quantizes when altermagnetism exceeds sp-hybridization while spin Hall quantizes when Rashba SOC is weaker, with both independent of the other coupling and arising from Fermi-surface Berry curvature.
