Abstract
To provide a magnetoresistive sensor comprising at least one sensor element for measuring a magnetic field, and a magnet assigned to the sensor element, which has a simple structure and in which subsequent trimming for compensating an offset can be dispensed with, the magnet (14) has structures (18) which lead to a perpendicular guidance of magnetic flux lines (25) from the supporting magnet (14) in the sensing direction (y direction) at least in the sensitive area (26) of the sensor (100).
