Abstract
The effect of a current on spin-wave propagation in a magnet-supercond uctor layered structure is investigated experimentally. The phenomenon of nonreciprocal ''brightening'' of the structure is observed. It is shown that this phenomenon is due to the motion of hypervortices of ma gnetic flux in a Josephson medium.
