Magnetic equivalent of electric superradiance in yttrium-iron-garnet films

[摘要] Magnons are oscillating magnetic waves that can be engineered using nanoscale structures and are expected to have useful applications in future information processing and storage devices. Here, the authors investigate magnetic superradiance as a possible mechanism limiting the lifetime of the magnonic excitations in thin films.
