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.
EuAgAs exhibits a near-degenerate magnetic ground state with an observed antiferromagnetic order that DFT predicts can be tuned to altermagnetism under hydrostatic pressure of approximately 14 GPa.
Anisotropic surface spin waves with chirality-dependent positions and split constant-frequency contours are proposed as a measurable signature for A-type altermagnets.
Thin CrSBr on gold shows ferromagnetic interlayer coupling stabilized by electron transfer from the substrate, confirmed by direct magnetic imaging and supported by DFT and spectroscopy.
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.
