Solid-state techniques have been suggested as possible methods for cooling certain cryoelectric devices. Consequently, an investigation of the practicality of a combined Peltier (thermoelectric)-Ettingshausen (thermomagnetic) device, operating between 70°K and room temperature, has been made. The Peltier effect results when current flows in a circuit composed of two dissimilar materials [1–3]. Heat is absorbed at one junction, and evolved at the other. The Ettingshausen effect results when current flows in a single conductor at right angles to an applied magnetic field [4,5]. Heat will flow in the conductor in a direction mutually perpendicular to the magnetic flux and the current. Figure 1 illustrates both effects.
