The anomalous Nernst effect (ANE), one of the thermoelectric effects in a magnet, is recently attracting growing interest as it has great potential for the next generation of high-efficiency energy harvesting applications. However, reported thermopower of ANE is not enough for the applications to date. Thus, it is important to design a new class of materials that exhibit a large ANE. It has been reported that the ANE is enhanced by employing multilayer structures. In addition, the interlayer exchange coupling (IEC) is also interesting phenomenon in multilayer structures. Therefore, we are studying the effect of IEC on ANE in multilayer structures with different thicknesses of nonmagnetic spacer layer. In this contribution, the relationship between the AHE, ANE and IEC in Fe/Au/Fe trilayers is studied.
