A research team has demonstrated that thin films of ruthenium dioxide (RuO₂) exhibit altermagnetism—the defining property of what is now recognized as the third fundamental class of magnetic materials ...

There is now a new addition to the magnetic family: thanks to experiments at the Swiss Light Source SLS, researchers have proved the existence of altermagnetism. The experimental discovery of this new ...

A 2026 review published by Nature has tightened the criteria for what counts as genuine evidence of altermagnetism, a magnetic phase that has drawn intense speculation about faster, lower-power ...

For well over a century, our understanding of the magnetic world had been neatly compartmentalised into two categories: ferromagnetism and antiferromagnetism. Ferromagnetism, which is the familiar ...
