AI Insight
Physicists have experimentally confirmed the existence of altermagnetism, a third type of magnetic phase that exists alongside the previously recognized ferromagnetism and antiferromagnetism. A research team led by SLAC National Accelerator Laboratory provided conclusive experimental proof of this magnetic state, which has distinct geometric properties that set it apart from conventional magnetic materials. The findings, published in Science, resolve a longstanding question about the fundamental types of magnetism that can occur in materials without external influence.
Why it matters
This discovery expands our understanding of fundamental magnetic phases in materials and could lead to new applications in electronics, data storage, and quantum computing. The unique properties of altermagnetic materials may enable novel technologies that exploit their distinct geometric and magnetic characteristics.
Understand the Science
For decades, physicists recognized only two types of magnetism that occur in materials without external influence: ferromagnetism and antiferromagnetism. In findings published in Science, a team led by the U.S. Department of Energy’s SLAC National Accelerator Laboratory has delivered conclusive experimental proof of a third magnetic phase called altermagnetism.
