Dirac quadrupole altermagnets in 2D exhibit a topological orbital piezomagnetic effect from strain altering their quadrupole Dirac points.
Sliding bilayer altermagnets host antiferromagnetic half-metallicity and Chern insulator phases via spin-dependent interlayer hopping in ferrovalley states, demonstrated in V2OSSe by first-principles calculations.
Interlayer sliding in M2A2B and M2AA'B bilayer altermagnets induces ferrovalley polarization and antiferromagnetic half-metallicity, with Mo2O2O showing 0.31 eV valley splitting and V2SSeO as a candidate half-metal.
2D spin-antiferroelectric altermagnets such as monolayer (CoCl)2Te are predicted to show giant spin splitting with spin currents switchable by in-plane electric field angle when hole-doped or gate polarity when electron-doped.
Terahertz optorbitronics tracks non-equilibrium orbital currents on femtosecond timescales, addressing conflicting reports on their propagation distances and suggesting control methods via materials like graphene and altermagnets.
A review that classifies two-dimensional altermagnets via spin-group theory, lists materials with large spin splitting, and outlines design strategies for experimental realization.
