Title:
POSITION DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/021876
Kind Code:
A1
Abstract:
A position detection device includes: a magnetic body layer having magnetization; an electroconductive film containing a material having spin orbit interaction; and a position information input unit. With the information input unit, when the temperature in the magnetic body layer is modulated and a spin Seebeck effect is induced, an electrical field is generated locally in the electroconductive film, and the temperature modulation position is detected from the resulting change in potential.
