On a Possibility to Measure Thermo-Electric Power in SNS Structures

Аннотация

Two dissimilar Josephson junctions, which are connected to a heater can act as precise batteries. Because of the di erencein thermoelectric power of these batteries, circuit with two dissimilar batteries, under heat flow ΔT~10 -5 K would have a net EMF 10 -11 V around the zero-resistance loop leading to a loop's time-varying magnetic flux. It is shown that its theoretical value is proportional to both the temperature difference as well as the disparity in the thermoelectric powers of the two junctions.
