Researchers observe chiral-spin rotation of non-collinear antiferromagnets
Researchers at Tohoku University and the Japan Atomic Energy Agency (JAEA) have reported a new spintronic phenomenon â a persistent rotation of chiral-spin structure.
The researchers studied the response of chiral-spin structure of a non-collinear antiferromagnet Mn3Sn thin film to electron spin injection and found that the chiral-spin structure shows persistent rotation at zero magnetic field. Moreover, their frequency can be tuned by the applied current.
