Title:
THERMOELECTRIC CONVERSION ELEMENT AND THERMOELECTRIC CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/224091
Kind Code:
A1
Abstract:
This thermoelectric conversion element (1) is made of a material that can be magnetized in any direction in a zero magnetic field, has a rectangular shape extending in one direction (y direction), and is magnetized in the +z direction. When heat flow Q (∝−∇T) flows in the +x direction through the thermoelectric conversion element (1), a temperature difference occurs in the +x direction. As a result, due to the abnormal Nernst effect, the thermoelectric conversion element (1) generates an electromotive force V(∝M×(−∇T)) in the direction of the cross product (y direction) orthogonal to both the direction of heat flow Q (+x direction) and the direction of magnetization M (+z direction). Examples of materials for the thermoelectric conversion element (1) include a ferrimagnetic material of which the compositional formula is R2Co7 (R is a rare earth element).
