Abstract = {{High quality thin films of the ferromagnetic semiconductor EuO have been
   prepared and were studied using a new form of spin-resolved
   spectroscopy. We observed large changes in the electronic structure
   across the Curie and metal-insulator transition temperature. We found
   that these are caused by the exchange splitting of the conduction band
   in the ferromagnetic state, which is as large as 0.6 eV. We also present
   strong evidence that the bottom of the conduction band consists mainly
   of majority spins. This implies that doped charge carriers in EuO are
   practically fully spin polarized.}},
