Abstract
The present disclosure relates to a magnetic sensor device having at least one magneto-resistive structure. The magneto-resistive structure comprises a magnetic free layer configured to generate a closed flux magnetization pattern in the free layer, and a magnetic reference layer having non-closed flux reference magnetization pattern; and a magnetic flux concentrator configured to increase a flux density of an external magnetic field in the magnetic free layer.
