(Color online) XRD patterns of Eu0.98Ce0.02O1−x film.
(Color online) Magnetization as a function of temperature of EuO, EuO1−x , and Eu0.98Ce0.02O1−x films grown by PLD in vacuum and under H2 flow.
(Color online) Derivative of the magnetization as a function of temperature of EuO, EuO1−x , and Eu0.98Ce0.02O1−x films.
(Color online) The combined photoemission (left) and inverse photoemission (right) of (a) EuO (100) and (b) Eu0.98Ce0.02O1−x (100).
The angle-resolved photoemission intensities at the Fermi level for Eu0.98Ce0.02O1−x (100), using a photon energy of 25 eV. The increase in intensity is indicative of electron pocket formation at the Brillouin zone edge along the Γ to X of the surface Brillouin zone.
Comparison of lattice constants and Curie temperatures for EuO, EuO1− x , Eu0.9 6Gd0.0 4O,a Eu0.9 6Gd0.0 4O1− x ,a and Eu0.9 8Ce0.0 2O1− x .
