Abstract
Method for sensing an external magnetic field using a magnetic sensor cell including: a magnetic tunnel junction including a reference layer having a reference magnetization oriented parallel to the plane of the reference layer, a sense layer having a sense magnetization, and a tunnel barrier layer between the sense and reference layers. A field line is configured for passing a field current for providing a sense magnetic field adapted for aligning the sense magnetization. The sense layer magnetization is orientable between a direction parallel to the plane of the sense layer and a direction perpendicular to the plane of the sense layer when the sense magnetic field is provided. The external magnetic field includes an in-plane component oriented parallel to the plane of the sense layer and an out-of-plane component perpendicular to the plane of the sense layer. The method includes sensing the out-of-plane component; and sensing the in-plane component.
