| Abstract: | In the systems Co/1bRu/1bO and Co/1bIr/1bO cubic spinel type phases of composition Co3?xRuxO4 (～0, 4≤ x ≤1) and Co2,5Ir0,5O4 have been synthesized. The cobalt can be partially substituted by iron and manganese (Co2,3?yMyRu0,7O4; 0≤y～0,7; M = Mn, Fe) or copper. By vibrational spectroscopic investigations a transition from low to high concentration of free electrons can be detected. |
