Layered cobalt oxides and heavy-fermion compounds are quantitatively compared from the viewpoint of thermoelectric materials. These two systems exhibit anomalously large thermopowers with good electric conductivity, which is attributed to a strong electron-electron correlation. In certain materials the pseudogap increases at low temperature, which further enhances the thermopower.
