Researchers have published new findings in the journal Science Advances detailing the unique properties of altermagnets. These materials feature magnetic moments that alternate in direction, allowing them to cancel out stray magnetic fields.
Why it matters
Altermagnets offer a promising pathway to control spintronics, which could enable information processing with significantly lower energy requirements than current standard technologies.
Altermagnets differ from standard magnets by forcing magnetic moments into alternating directions, providing a mechanism to steer electrons with opposite spins along distinct paths through magnetic patterns.
