Abstract:
The present invention provides an appropriately produced magnetic material sensor having a small size.The magnetic material sensor of this invention includes: a magnetoresistive effect film, formed using magnetic films; a current source, for supplying to the magnetoresistive effect film a current having a magnitude and a direction that can change the magnetization directions of the magnetic films; and a detector, for detecting the resistance of the magnetoresistive effect film.
