Anomalous hall sensor and anomalous hall

Abstract

The present disclosure relates to an anomalous Hall sensor, including a Hall cross. The Hall cross includes a layer stack including a ferromagnetic layer. A first arm of the Hall cross formed in the layer stack extends in a first direction. A second arm of the Hall cross formed in the layer stack extends in a second direction perpendicular to the first direction. The anomalous Hall sensor includes a control circuit configured to apply current through the first arm and measure voltage across the second arm, and apply current through the second arm and measure voltage across the first arm. The anomalous Hall sensor further includes a processor configured to compute a component of an external magnetic field in a third direction perpendicular to the first and the second direction based on a combination of the measured voltages.
