Spin caloritronics based on the spin Seebeck effect (SSE) has the potential to impact advanced spintronics, thermoelectric devices and waste heat recovery for power generation. We present systematic studies on yttrium iron garnet (YIG) and demonstrate the influence of in-plane and out-of-plane magnetic anisotropy as well as switching on the longitudinal SSE in this material. We also show that the introduction of intermediate C60 organic layer improves the SSE voltage by several orders of magnitude over a wide temperature range. The enhancement of SSE voltage showed a direct correlation with spin diffusion length of C60, and spin mixing conductance at interface between the FM and NM. In addition, we also show how in FM metals the Anomalous Nernst effect (ANE) signal can dominate over the SSE. Overall, we will discuss how studies and optimization of SSE and ANE in magnetic oxides could lead to the development of energy-efficient thermomagnetic devices.
