Title:
THERMOELECTRIC CONVERSION ELEMENT AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2018/146713
Kind Code:
A1
Abstract:
The purpose of the present invention is to implement stable thermoelectric conversion operation in a convenient manner in a thermoelectric conversion element (21) in which a spin-Seebeck effect and an anomalous Nernst effect are used in combination. A thermoelectric conversion element of the present invention comprises: a stacked film (23) of a magnetic metal film (21) which generates a first electromotive force due to a temperature gradient in a film-thickness direction (Z), and an antiferromagnetic metal film (22) which is stacked on the magnetic metal film to fix a magnetization direction of the magnetic metal film in one direction (y) in a film plane, and which generates a second electromotive force due to injection of a spin current of the magnetic metal film caused by the temperature gradient in the film-thickness direction; and a pair of terminals (24) disposed side by side and spaced apart from each other in a direction (x) different from the magnetization direction on the film plane of the stacked film.
