Anomalous Nernst effect (ANE)-based heat flux sensors offer multiple advantages owing to their simple structures. For their practical application, both a large anomalous Nernst coefficient and a high coercive force are indispensable. Rare earth transition metal alloy films exhibit a large SANE and high coercive force near the magnetization compensation point. However, a discrepancy exists between the composition that yields the maximum SANE and the magnetization compensation point. In this study, with the aim of control of magnetization compensation point, we fabricated Tb-Co-Cr thin films by adding Cr to a Tb-Co alloy. As a result, we successfully confirmed that the addition of Cr shifts the magnetization compensation point toward a lower Tb concentration region.
