Title:
MAGNETIC FIELD MEASUREMENT DEVICE AND MAGNETIC FIELD MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2013/153949
Kind Code:
A1
Abstract:
A magnetic field measurement device is provided with a magnetic body layer, an electricity-generating layer and a magnetic field information generation section. The electricity-generating layer is formed on the magnetic body layer, and is formed from a material that exhibits spin-orbit interaction. On the basis of information about an electromotive force generated in the electricity-generating layer, the magnetic field information generation section generates magnetic field information about a magnetic field applied to the magnetic body layer.
