As of May 2026: Theoretical prediction and experimental confirmation of altermagnetism

A team in Japan just proved that ultra-thin films of ruthenium dioxide exhibit altermagnetism—a third fundamental class of magnetism that wasn't confirmed 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.
