Magnon mechanism of Josephson coupling in SFS structures
  It is shown that Josephson coupling in SFS junction due to electron-magnon interaction remains at a distance, when the usual proximity effect decreases exponentially. We obtain expression for the Josephson energy, which contain the parameters of the magnon spectrum and allow to estimate the value of the maximum superconducting current.
