• The carrier contribution to the generation of spin waves in ferromagnetic semiconductors under perpendicular pumping conditions is discussed. It is shown that for degenerate semiconduct this electronic contribution predicts a threshold pumping power of the same order of magnitude as the one involved in the direct mechanism of spin waves excitation. Also the carrier assisted mechanism excites spin waves with k in a broad range of values in contrast with the direct mechanism.
