摘要：

Electrical conductivity and powder X-ray studies have been made on (Sr1-alphaNa[alpha])CoOx after firing at 980-degrees-C in air. The data are explainable in terms of the mixed phase of SrCoO4; (x is similar to 2.5) and NaCo2O4. We found a distinct metallic conductivity in NaCo2O4; the resistivity decreases linearly to 12 K from room temperature. This compound may be another candidate mother oxide for future study of high-temperature superconductivity.
