We studied magnetotransport property for the layered cobalt oxide BaCo6O11, which was recently reported as a novel compound with isostructure of magnetoplumbite-derived oxide of SrCo6O11. A polycrystalline sample of BaCo6O11 exhibits metallic behavior in the electrical resistivity below the ferromagnetic transition temperature of 11.5 K. A tunneling-type magnetoresistance up to −20% was observed at 11.5 K and 90 kOe. These observations propose a half-metallic electronic state for BaCo6O11.
