Title:
位置検出装置
Document Type and Number:
Japanese Patent JP5828341
Kind Code:
B2
Abstract:
A position detection device includes a thermoelectric conversion portion which includes a magnetic layer and a plurality of electrodes. The magnetic layer has magnetization. The plurality of electrodes are formed of a material having spin-orbit interaction, and are formed on the magnetic layer so as to extend in a direction which intersects with the magnetization direction of the magnetic layer. When an arbitrary location on the layer-surface of the magnetic layer is heated, the thermoelectric conversion portion modulates the effective temperature in the magnetic layer and induces a spin Seebeck effect. As a result, the thermoelectric conversion portion generates, from the plurality of electrodes, a voltage corresponding to the heated position as position information.
