Experiments are reviewed in which strong linear excitation of magnons by ac currents in Fe/Cr/Fe trilayers are observed through Brillouin light scattering. The scattering intensity is investigated as a function of the magnon wave number and applied magnetic field, thus providing strong evidence for
