Anomalous Nernst thermoelectric generation in multilayer-laminated coiled magnetic wires

Abstract

Thermoelectric generation using the anomalous Nernst effect is demonstrated in multilayer-laminated coils comprising ferromagnetic metal wires stacked in the radial direction. By applying a temperature gradient to the coils in the radial direction, the thermoelectric voltage and power induced by the anomalous Nernst effect appear and increase in proportion to the number of the stacked layers. This device structure is useful for improving the thermoelectric performance and versatility of energy harvesting devices based on the anomalous Nernst effect.
