Abstract
A magnetic sensor includes: a substrate; and first and second magnetoresistive devices on one surface of the substrate. Each of the first and second magnetoresistive devices includes: a fixed layer having an easy magnetization axis perpendicular to the one surface and having a fixed magnetization direction; a free layer having a variable magnetization direction; and an intermediate layer made of a non-magnetic material and arranged between the fixed layer and the free layer. The fixed layer includes a first ferromagnetic layer, a second ferromagnetic layer, and a non-magnetic layer arranged between the first ferromagnetic layer and the second ferromagnetic layer.
