Abstract

[Object] To provide a thermoelectric body that can be deposited on any substrate, which is not limited to a single crystal bulk material or an epitaxially grown thin film, and is capable of exhibiting high coercive force and residual magnetization with respect to in-plane magnetization. [Solving Means] A thermoelectric body that is a magnetic film for use in a thermoelectric generation element utilizing an anomalous Nernst effect, characterized by having an easy axis of magnetization in an in-plane direction and an amorphous structure. Favorably, the thermoelectric body is characterized in that SmpCo100-p (0<p≤50) or Smp(FeqCo100-q)100-p (0<p≤50, 0≤q≤100) is included.
