CrSb is a high-temperature metallic altermagnet with coherent magnons of group velocities 61 and 58 km/s that exhibit chiral momentum-space splitting, described by a minimal Heisenberg model with alternating exchange interactions.
In a V-shaped 1D chain the nonmagnetic magnetoelectric response peaks near apex angle 0.6π because geometry induces an effective spin-orbit term whose angular factor sinθ sin(θ/2) matches Kubo-formula numerics.
V2O-based altermagnets enable robust spin-polarized specular Andreev reflection in superconductor junctions, detectable via nonlocal conductance in a multiterminal geometry.
Multipole analysis of α-MnTe shows that distinct altermagnetic configurations induce spin-momentum locking with different parities and magnetic spin Hall effects with up to 16% angle, enabling identification of order parameters via anisotropy.
