Macroscopic altermagnetic domains in MnTe were visualized as two distinct time-reversal symmetry breaking regions with large Kerr rotations independent of net magnetization, controllable by external stimuli.
Derivation of spin-current high-harmonic selection rules that distinguish altermagnetic spin-group phases from ferromagnetic, antiferromagnetic, and magnetic-point-group mimics under different light polarizations in the weak-SOC regime.
Altermagnets exhibit a resonant third-order intrinsic anomalous Hall effect from the Berry curvature quadrupole, serving as a quantum geometric transport fingerprint.
A novel KKR-based ab initio scheme for dynamical magnetic susceptibility in non-collinear magnets is developed and applied to reveal non-monotonous magnon damping in Mn3Ir.
Antiferromagnetic skyrmions exhibit bidirectional motion under current-induced torques above a threshold due to competing effective forces, enabling logic gates.
SHG in CoF2 is shown to be sensitive to the ferroic-octupolar magnetic order parameter in the altermagnetic phase via resonant three-photon processes and symmetry-allowed quadrupolar polarization.
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
Relativistic altermagnets exhibit mixed g-, d-, and p-wave spin-momentum locking with symmetry-protected nodal planes and accidental nodal surfaces depending on Néel vector orientation.
Compensated ferrimagnets with exchange-coupling asymmetry produce robust spin Seebeck currents comparable to ferromagnets via isotropic magnon splitting, while the effect vanishes in altermagnets.
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.
Charge disproportionation stabilizes the monoclinic semiconducting state in Fe₂PO₅ and enables its room-temperature d-wave altermagnetism.
Altermagnets enable planar Josephson junctions that host Majorana end modes controlled by crystallographic orientation, extending naturally to high-Tc platforms.
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.
Strain engineering drives altermagnetic-to-ferrimagnetic transitions and activates anomalous transport responses in RuO2 and MnF2 via symmetry breaking.
A minimal 2D d-wave altermagnetic model with band inversion realizes a ferroelectrically tunable Chern insulator with spontaneous spin canting, enabling C = ±1 and ±2 phases via Berry-curvature reorganization.
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.
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.
The paper reviews applications of rotational anisotropy second harmonic generation to identify crystallographic, magnetic, and hidden order parameters across condensed matter systems.
