Extensive study on the magnetic thin films has been performed aiming high anomalous Nernst effect (ANE). ANE in ferromagnets and antiferromagnets has been widely investigated, whereas Mn₄N thin films are examined in this study to open a pathway for ANE of ferrimagnets. Note that it is known that the Mn₄N shows small saturation magnetization and strong perpendicular magnetic anisotropy. As a result of measurement, the relatively high ANE voltage was observed, and further improvement of ANE was suggested by the analysis based on the anomalous Hall effect.
