We demonstrate experimentally the ability to control by electric current the phase and the wavelength of spin waves propagating in submicrometer magnetic waveguides. The dependence of the spin-wave characteristics on the current and on the excitation frequency was determined by phase-resolved microfocus Brillouin light scattering spectroscopy. We show that moderately small currents are sufficient to induce nearly twofold changes of the wavelength and spin-wave phase shift of more than +/-pi radians over a propagation distance of several micrometers.
