"The Anomalous Metallic Ferromagnetic State of Sr Doped Manganites"
V. Ferrari, M.J. Rozenberg and R. Weht
Mod. Phys. Lett. B 15(23) (2001) 1031-1040
We deduce a model relevant for the anomalous metallic state of Sr doped manganites at low temperatures within the ferromagnetic phase. It provides a natural explanation for several anomalous features observed experimentally, such as the small Drude contribution in optical conductivity, the “pseudo-gap” in the density of states, and the unusual dispersion observed in photoemission.
