... the Mn ions. There is broad agreement that ferromagnetism is due to carrier mediated interactions between the Mn ions. Strong magneto-transport effects8 and tunneling magnetoresistance9 support this point of view and demonstrate that the valence band holes are strongly coupled to the Mn ions. The ph ...
