Research Abstract

This research aimed to clarify the physical mechanism of anomalous Nernst effect and to demonstrate an application of the effect to thermoelectric conversion devices. Magnetic anisotropy dependence and temperature dependence of anomalous Nernst effect were precisely investigated. The thermopile device including FePt wires enhanced the anomalous Nernst voltage effectively, which paves the way for realizing novel thermoelectric applications employing the anomalous Nernst effect.
