A magnetic sensor cell (1) comprises a magnetic tunnel junction (2) comprising a reference layer (23) having a reference magnetization (230) oriented substantially parallel to the plane of the reference layer (23), a sense layer (21) having a sense magnetization (210), and a tunnel barrier layer (22) between the sense and reference layers (21, 23); and a magnetic device (4) configured for providing a sense magnetic field (42) adapted for aligning the sense magnetization (210). The sense layer magnetization (210) is orientable between a direction parallel to the plane of the sense layer (21) and a direction perpendicular to the plane of the sense layer (21) when the sense magnetic field (42) is provided. The magnetic sensor cell can be used for sensing an external magnetic field comprising a component (451) oriented parallel to the plane of the sense layer and a component (452) oriented perpendicular to the plane of the sense layer. |
