Experimental Evidence Supports New Form of Magnetism, 'Altermagnetism'

Scientists have reported experimental evidence for 'altermagnetism,' a novel type of magnetism, in cobalt-intercalated tantalum diselenide. Unlike known ferromagnets or antiferromagnets, altermagnets lack net magnetization but exhibit spin-dependent electron behavior. This discovery could pave the way for more efficient spintronic devices, impacting future technology.
