摘要：

A transition-metal oxide NaCo2O4 is a layered oxide in which CoO2 and Na alternately stack along the c axis. Recently we have found that this compound shows large thermopower with low resistivity, which is comparable to those of Bi2Te3. The negative transverse magnetoresistance and the strongly temperature-dependent; Hall coefficient suggest that electron correlation dominates the conduction mechanism in NaCo2O4.
