ABSTRACT:
A thermoelectric material is provided which consists of an oxide with a perovskite structure, wherein the oxide is of the formula (Ln.sub.1-x A.sub.x).sub.2 MO.sub.4 with 0.01.ltoreq.x.ltoreq.0.05, where Ln is a rare earth element, A is an alkali earth metal element, and M is a transition metal element. The thermoelectric material is particularly useful for Peltier cooling elements to produce low temperatures below room temperature.
