    Abstract: In a recent Letter [1] we developed a theory of carrier-induced ferromagnetism in diluted magnetic semiconductors. We analyzed the elementary spin excitations at low temperatures, where spin waves can be approximated as noninteracting Bose particles (“independent spin-wave theory”). In addition, we proposed a simple ad hoc “self-consistent spin-wave approximation” for higher temperatures to demonstrate the increasing inadequacy of mean-field theory critical temperature
    estimates at high carrier densities.
