Abstract
Official abstract text for this publication.
A magnetic sensor includes: a first magnetic detection element group and a second magnetic detection element group each of which including a plurality of self-pinned magnetoresistive effect elements; and a first control unit and a second control unit configured to respectively process detection signals detected from a magnetic field by the magnetoresistive effect elements of the first magnetic detection element group and the second magnetic detection element group, in which pinned magnetization directions of at least two magnetoresistive effect elements in the first magnetic detection element group and the second magnetic detection element group are different from each other, and the plurality of magnetoresistive effect elements of the first magnetic detection element group and the plurality of magnetoresistive effect elements of the second magnetic detection element group are arranged so that the magnetization directions thereof are symmetrical.
First claim
Opening claim text (preview).
1 . A magnetic sensor comprising: a first magnetic detection element group and a second magnetic detection element group each of which include a respective plurality of magnetoresistive effect elements each in which a fixed magnetic layer and a free magnetic layer are laminated with a non-magnetic material layer interposed therebetween; and a first control unit and a second control unit configured to respectively process detection signals detected from a magnetic field by the magnetoresistive…
