The third magnetic state: racing to build AI-era memory

New Capabilities

First predicted altermagnetism in 2019

A team in Japan just proved that ultra-thin films of ruthenium dioxide exhibit altermagnetism—a third fundamental class of magnetism that remained hidden in plain sight until 2019. The breakthrough combines the stability of antiferromagnets with the fast electrical readout of ferromagnets, addressing the core limitation that keeps magnetic memory slow and bulky.
