Abstract:
1. A magnetoresistive device, comprising: a carrier; an xMR-sensor formed on or in the carrier, the xMR-sensor based on an anisotropic magnetoresistance (AMR) effect, a giant magnetoresistance (GMR) effect, or a tunnel magnetoresistance (TMR) effect; a hard magnetic layer distinct from the xMR-sensor and formed above an active xMR-region of the xMR-sensor; and an insulating layer distinct from the xMR-sensor and arranged between the xMR-sensor and the hard magnetic layer, wherein the hard magnetic layer is configured to provide a bias magnetic field in the active xMR-region of the xMR-sensor from a position above the xMR-sensor along the easy axis of the xMR-sensor, and wherein a vertical distance between the xMR-sensor and the hard magnetic layer is smaller than a lateral dimension of the hard magnetic layer.
