Abstract
A magnetoresistive sensor includes a magnetic reference layer. The magnetic reference layer includes a permanent closed flux magnetization pattern of a predetermined rotational direction. Furthermore, the magnetoresistive sensor includes a magnetic free layer. The magnetic free layer has a total lateral area that is smaller than a total lateral area of the magnetic reference layer. A centroid of the magnetic free layer is laterally displaced with respect to a centroid of the magnetic reference layer.
