December 22 , 2025 16 hrs 0 min 5 0
  • 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 (RuO) 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 RuO thin films.
