Effects of spin current. a, b Representative BLS spectra recorded at I = −20 and 20 mA, respectively, together with the reference spectrum obtained at I = 0. c Current dependences of the BLS intensity integrated over the measured spectrum (solid squares) and of the frequency of the lowest-energy magnon state ν min (open squares). Solid curve is a guide for the eye. Dashed line shows the calculated variation of ν min due to the Oersted field of the current. The data were obtained at H 0 = 200 Oe
