Title (EN) THERMOELECTRIC CONVERSION ELEMENT
(FR) ÉLÉMENT DE CONVERSION THERMOÉLECTRIQUE
(JA) 熱電変換素子
Abstract:
(EN) This thermoelectric conversion element 10 comprises an anomalous Nernst material 11 exhibiting an anomalous Nernst effect, the anomalous Nernst material 11 containing at least an element exhibiting an inverse spin Hall effect, and the element being spin-polarized. Applying, for example, a magnetic field in the x direction and a temperature gradient in the z direction to such a thermoelectric conversion element 10, allows a thermoelectromotive force to be extracted from terminals 12.
(FR) L'invention concerne un élément de conversion thermoélectrique (10) comprenant un matériau de Nernst anormal (11) présentant un effet Nernst anormal, le matériau de Nernst (11) anormal contenant au moins un élément présentant un effet Hall à spin inverse, et l'élément étant polarisé par spin. L'application, par exemple, d'un champ magnétique dans la direction x et d'un gradient de température dans la direction z à un tel élément de conversion thermoélectrique (10), permet d'extraire une force thermoélectromotrice des bornes (12).
(JA) 熱電変換素子10は、異常ネルンスト効果を発現する異常ネルンスト材料11を備え、異常ネルンスト材料11は、逆スピンホール効果を発現する元素を少なくとも含み、かつ該元素がスピン偏極している。このような熱電変換素子10に対して、例えば、x方向に磁場、z方向に温度勾配をそれぞれ印加することで、端子12から熱起電力を取り出すことができる。
