Complex cobalt oxide perovskite-derived compounds with a general formula LnBaCo_2O_{5+x} (Ln = rare earth) attracted considerable interests because of their interesting properties: magnetic and metal-insulator transitions, giant magnetoresistance, ionic conductivity, and a structural similarity to high temperature superconductors. All the compounds are oxygen non-stoichiometric (0
