We report an x-ray absorption spectroscopic (XAS) study on thin films of ${\mathrm{La}}_{0.7}{\mathrm{Ce}}_{0.3}{\mathrm{MnO}}_{3}.$ The measurements clearly show that the cerium is in the Ce(IV) valence state, and that the manganese is present in a mixture of ${\mathrm{Mn}}^{2+}$ and ${\mathrm{Mn}}^{3+}$ valence states. These data demonstrate that ${\mathrm{La}}_{0.7}{\mathrm{Ce}}_{0.3}{\mathrm{MnO}}_{3}$ is an electron-doped colossal …
