  The interaction between a spin polarized dc electrical current and spin wave
modes of a cylindrical nanowire is investigated in this report. We found that
close to the critical current, the uniform mode is suppressed, while the edge
mode starts to propagate into the sample. When the current exceeds the critical
value, this phenomenon is even more accentuated. The edge mode becomes the
uniform mode of the nanowire. The higher spin wave modes are slowly pushed away
by the current until the propagating mode remains.
