Abstract
A magnetic sensor device comprising a plurality of magnetic sensor elements; each magnetic sensor element including a magnetic tunnel junction including a reference layer having a reference magnetization, a sense layer having a sense magnetization and a tunnel barrier layer; the sense magnetization comprising a stable vortex configuration in the absence of an external magnetic field, the vortex having a core reversibly movable in a plane (P) of the sense layer according to an external magnetic field; the sense layer including a peripheral shape in the plane (P), the peripheral shape including an asymmetric edge portion; the magnetic sensor elements being arranged such that the edge portion of a magnetic sensor element is opposite to the edge portion of the adjacent magnetic sensor element.
