The anomalous Nernst effect (ANE) is expected as the new energy harvesting technology. The effect is defined as a generation of an electric field in the vertical direction to the magnetization of the sample and the applied temperature gradient. To realize the ANE devices, searching materials which have large ANE conversion efficiency and studying the thermoelectric transport property have attracted significant attention. In this study, we found that Ge doped Co thin films have large ANE compared to pure Co thin films and researched the mechanism of enhancement of ANE in CoGe thin films.
