Caught by chirality.

Altermagnets can be identified by the handedness of their collective magnetic excitations, using chirality as the distinguishing feature.

• Why it matters: A practical way to classify altermagnets is needed because their magnetic excitations carry a specific symmetry signature.
• What they did: The work proposes using the chirality, or handedness, of collective magnetic excitations as the identifying criterion for altermagnets.
• The result: Chirality-linked excitation handedness provides a basis for identifying altermagnets and distinguishing them via their excitation properties.
