ABSTRACT:
The present invention provides a complex oxide having a composition represented by the formula La1−xMxNiO2.7−3.3or (La1−xMx)2NiO3.6−4.4(wherein M is at least one element selected from the group consisting of Na, K, Li, Zn, Pb, Ba, Ca, Al, Nd, Bi and Y, and 0.01≦×≦0.8), the complex oxide having a negative Seebeck coefficient at 100° C. or higher. This complex oxide is a novel material which exhibits excellent properties as an n-type thermoelectric material.
