The anomalous Nernst effect (ANE) and the spin Seebeck effect (SSE) in spin caloritronics are two of the most important mechanisms to manipulate the spin-polarized current and pure spin current by thermal excitation. Nevertheless, a recent research work suggests that the thermal Hall effect (THE) have field dependences indistinguishable from, and may even overwhelm, those of the ANE and SSE. Therefore, it is vital to investigate the contribution of the THE in the ANE and SSE.

In this work, we show that the thermocouple effect is indeed inevitable in the ANE and SSE configuration. By using several special measurement geometries, we are able to compare the magnitude of the THE with that of the ANE in Py and that of the SSE in YIG. Our results show that the contribution of the THE by the thermal couple effect in the Py and YIG is negligibly small. The spin-polarized current in the ANE and the pure spin current in the SSE remain as indispensable elements to explore these two spin caloritronics phenomena. Our work will be very useful to study the THE in materials with inversion symmetry breaking.
