Contrary to predictions of a ferromagnetic semiconducting ground state obtained by density-functional calculations, dynamical correlations induce a closing of the gap and produce a half-metallic ferromagnetic state. These results emphasize the importance of dynamic correlations in materials suitable for spintronics.Published in Phys. Rev. Lett. 96, 197203 (2006)Strongly Correlated ElectronsMaterials Sciencetext
