    • We performed the redox-titration experiments for two times, and obtained the cobalt valences 2.93 and 2.94, respectively. The experimental error is estimated to be ±0.04

    • From this simulation, we confirmed that the strong preferred orientation exists in the XRD pattern. In Fig. 2, the intensities of 0 0 8 0, 0 0 1 0 0, and 0 0 1 2 0 lines look rather small at glance; however, they are also enhanced as good as the 0 0 2 0, 0 0 4 0, and 0 0 6 0 lines at lower angles. Because of this strong preferred orientation, we could not reproduce perfectly the intensities of all reflections, especially for 0 0 8 0 (∼41.8°) and 0 0 1 0 0 (∼53.0°) reflections in Fig. 7

    • Below about 80 K, resistivity increase rapidly strays out of any conduction mechanisms. We conceive that this is not intrinsic property of the present phase and is due to the problems of the measurement system on measuring the high-resistance sample. In this paper, we do not discuss the resistivity data in the temperature range
