Title:
POSITION DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/153642
Kind Code:
A1
Abstract:
A position detection device comprises a thermoelectric conversion unit which includes a magnetic layer (2) and a plurality of electrodes (5, 6). The magnetic layer (2) has magnetization. The plurality of electrodes (5, 6) are formed from a material having spin-orbit interaction, and are formed on the magnetic layer (2) so as to extend a direction which intersects with the magnetization direction of the magnetic film (2). Due to an arbitrary part of the layer-surface of the magnetic layer (2) being heated, the thermoelectric conversion unit modulates the effective temperature in the magnetic layer (2) and induces a spin Seebeck effect. As a result, the thermoelectric conversion unit generates, from the plurality of electrodes (5, 6), a voltage, corresponding to the heated position, as position information.
