Magnetization, transport, and muon spin relaxation measurements provide evidence for altermagnetic order in Fe0.85Cr0.15Sb2 below ~3.5 K with time-reversal symmetry breaking but no net magnetization.
Altermagnets exhibit a resonant third-order intrinsic anomalous Hall effect from the Berry curvature quadrupole, serving as a quantum geometric transport fingerprint.
Altermagnets provide all-electrical, dephasing-protected spin qubits in quantum dots with tunable frequencies via dot ellipticity and support for fSim gates plus singlet-triplet operation.
Altermagnets enable planar Josephson junctions that host Majorana end modes controlled by crystallographic orientation, extending naturally to high-Tc platforms.
Strain engineering drives altermagnetic-to-ferrimagnetic transitions and activates anomalous transport responses in RuO2 and MnF2 via symmetry breaking.
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.
