In this article, consortium members from CNRSand Thales achieved efficient spin-waves propagation in a prototypicalinsulating antiferromagnets. They demonstrated that the presence ofnon-degenerated dipolar exchange spin-waves detected by both inductive andspintronic transducers. The electrical detection of coherent nonreciprocalantiferromagnetic spin-waves paves the way for the development of faster andmore field secured magnonic devices based on antiferromagnetic materials. Theseresults were published in the journal SciencesAdvances 9 (32), eadh1601 (2023).Next step will be to integrate antiferroic skyrmions under developments inTSAR.
