Briefings

A research team led by SLAC National Accelerator Laboratory confirmed the existence of altermagnetism, a third magnetic phase distinct from ferromagnetism and antiferromagnetism. The study, published in Science, provides experimental proof of this new phase through geometric twisting in materials. This discovery expands the known classification of magnetic states in condensed matter physics.

Key points

• A team led by the U.S. Department of Energy's SLAC National Accelerator Laboratory confirmed altermagnetism via experimental proof published in Science.
• Altermagnetism is a third magnetic phase characterized by geometric twisting, differing from the previously recognized ferromagnetism and antiferromagnetism.

Context

This finding expands the classification of magnetic states in condensed matter physics, challenging the long-held view that only two magnetic phases exist without external influence.

Limitations

The evidence is limited to the specific experimental proof of altermagnetism described in the Science publication. No additional background on the discovery's implications or future applications is supplied.
