Query: Electronic structure of (Ga,Mn)As revisited: an alternative view on the
  "Battle of the bands"   New detailed angle-resolved photoemission data are presented, revealing the
existence of an Mn-induced state that extends into the band gap of GaAs. In
sharp contrast to recent reports we observe that the state is highly
dispersive. Spin resolved photoemission shows that the band is spin polarized
even at room temperature. The results are not consistent with any of the
currently discussed band models for ferromagnetism.
