[Press Release] Giant Effective Damping of Octupole Oscillation in an Antiferromagnetic Weyl Semimet

Our collaborative research with colleagues in the University of Tokyo, Tohoku University, and RIKEN reported the first observation of the time-resolved octupole oscillation in Mn3Sn, an antiferromagnetic Weyl semimetal. This study also demonstrates the ultra-fast (10 picoseconds) spin-flip rate Mn3Sn, paving the path toward realizing ultrafast electronic devices using topological antiferromagnets.
