We report the observation of the spatiotemporal dynamics of coherent magnon-polaritons in multiferroic BiFeO₃ through time-resolved imaging measurements. The observed dynamics suggest that antiferromagnetic magnons can propagate over long distances, up to several hundred micrometers, through strong coupling with photons.
