Kind: research · Impact: medium

## In brief

- A photonic crystal reproduces the spin-split band behaviour of altermagnets using circular polarization as a spin analogue.
- Altermagnets have spin-split bands despite zero net magnetization, a symmetry-driven effect.
- The results were published online in Nature Physics on 11 November 2026.

## Why it matters

The work offers a photonic platform to study a symmetry-driven magnetic phenomenon that is hard to probe directly in magnetic materials, which may help researchers explore altermagnetic physics experimentally.
