Study of half-metallicity in LSMO

Self-interaction corrected local spin density approximation calculations were performed for La((1-x))SrxMnO3 (LSMO) (x = 0.7). A half-metallic state was obtained for LSMO with manganese configuration Mn3+, whilst Mn4+ gave rise to a metallic state with a negligible spin polarization at the Fermi level. (C) 2004 Elsevier B.V.
