- The Japanese researchers have experimentally confirmed ruthenium dioxide as an altermagnet.
- Altermagnet is a third fundamental magnetic class distinct from ferromagnets and antiferromagnets.
- Ruthenium dioxide (RuO₂) thin films have been experimentally demonstrated to exhibit true altermagnetism.
- It will aid to develop next-generation high-speed, high-density magnetic memory devices utilizing RuO₂ thin films.
