| Research Abstract |
The single crystal/polycrystal sample of the transition metal oxides in which the crystal structure consisted of several crystallographically different coordination polyhedrons were produced, and the career characteristic was evaluated. Some characteristics such as the Seebeck coefficient, electrical conductivity, and electronic state calculation showed that the 2H-perovskite type calcium cobaltite and spinel-type ruthenium cobaltite were in the coexistence state of the hole and electron by the electron exchange reaction and disproportionation reaction between each site resulting from two or more mixed ionic states.
